hi guys today we will be doing another science video today we'll be making the mega fizz balloon for this experiment we need two funnels a plastic bottle a balloon bicarbonate of soda and 200 milliliters of malt vinegar so first we tip in the malt vinegar into the plastic bottle then we'll use the funnel to pour the bicarbonate of soda into the balloon and then when we have put it in we will hang it over the bottle without spinning it


[42.36]
well most of the bicarbonate of soda is in our balloon I am going to lift the balloon up tipping the baking soda into the into the vinegar and watch to see what happens


[60.82]
ready 3 2 1


[67.74]
Wow amazing its massive now stoical I can hear it fizzing literally all the vinaigrettes gone now the bicarbonate of soda in the malt vinegar have reacted together to make a gas which is inside this balloon can you hear that hi guys and welcome to another video today we're going to be doing some experiments with dry ice dry ice is carbon dioxide carbon dioxide is normally a gas but to get it to a solid in these few frozen to below minus 80 degrees for my first experiment I will be looking at the distance between hot and cold or to when it's mixed with dry ice now since the dry ice is below minus 80 degrees I'm rain my safety gloves do not try this at home let's put a dryer and then see how it reacts


[142.56]
now let's see how it reacts with coal


[160.09]
wallets so cool let's add just a bit more so-called egg it's going all over the table oh and look you can hear it too this is the carbon dioxide turning back into its gas firm now that's gone to the hot water but you know this is hot water so don't try this at home


[193.77]
whoa look at that so food


[203.28]
you or suppose as you see the hot water is a much bigger the action with the dry ice


[217.99]
as we see the cold water to react in much love where's the hot water with the public's and reaction but faster this is due to the amount of time much of carbon dioxide took to turn back into its Gustin now let's have a bit of fun with this one I'm going to add some food coloring so I think I'm going to go for red and then I'm going to add my hot water then let's add the dry ice


[255.709]
that was more reactive than I expected


[269.84]
due to adding much more dry ice it created a very aggressive reaction and as you can see we have a lot of red shards of ice stuck in the jar and as you can as you maybe can't tell it's kind of stuck to the table my neck to experiment I'm going to be expanding this balloon with dry ice so my first step is going I'm going to attach this balloon to the top of this hollow tube then I'm going to put my safety gloves on and get a bit of my dry ice


[311.919]
then I'm going to put a bit of water through YouTube since my balloon and then we've got one of my de to Nuggets head and put it it's merchants


[342.749]
the water is reacting with the dry ice to create the carbon dioxide which is making the balloon expand but let's let it go yay oh my gosh my next experiment I'm going to making bubble test shoots so this experiment I match going to need some test shoots so here my colorful test tube and first I'm going to put a bit of water in each of my question


[390.69]
so and then I'm going to put a little bit of my washing up liquid in each of my shoes


[423.82]
and then I'm going to get my dry ice with my steak before


[440.25]
and put a little bit in each one


[451.21]
as you see the dry ice has reacted with the washing-up liquid and the water inside the test chamber is making massive bubbles


[492.34]
when the bubbles come straight out of the test tube they're really cold from the dry ice but when they come in my hands they look a bit a similar thing is happening here in this experiment to all the other experiments the carbon dioxide is turning back into a gas and is mixing with the washing-up liquid which is making our bubbles my next experiment is going to be expanding this tiny balloon so the first step is getting some dry ice into the big bottle


[534.17]
now that all our dry ice is in the bottle we are going to pour some water in the dry I said you can see in the bottom is already reacting with the air so when we add the water let's see the big reaction make sure you have your balloon ready as it's going to start reacting as soon as I pull this one


[565.76]
look at the size of it


[586.04]
but let's go to fall for it Hudson Wow whoo that was amazing did you see the size of that balloon Wow now we're going to do it with hot water let's see how fast it expands so first is my safety gloves let's get our dry ice only does it still have some dry ice in the bottle now we are funnel


[637.759]
all right now let's get our hot water


[651.649]
we'll be ready put this on


[664.839]
Wow you


[705.32]
Wow oh sorry cool thank you for watching today's video guys what would your favorite experiment put it in the comments below my favor was the color one did you see that reaction it was massive don't forget to like this video and subscribe to the channel I'll see you next time bye hi guys and welcome to another video today we are going to be doing some bubble science looks like we can make loads of different shapes and sizes of bubbles we can make up here amid the cube and loads of different sizes I can't wait to get it on books and make some awesome bubbles so I think these are the different shapes you can make the cube and the pyramid and these poles and string look like a bit is what you make and the big big bubbles with and here is our bubble solution and this is what easy to make different shaped bubble one so to make the bubble solution any good scientist knows that you have to learn by making before I get started I'm gonna go get my science gear on ready step 1 pour bubble solution is the large cavity of the bubble trail Oh God holding the cubase edges place it into the solutions for that one face is submerged in the solution rather cube onto another face the first station now have a film of solution over I'm going to make the cube one first


[822.18]
I think that worked really well but they did pop quite easily don't know why though oh it says here why do bubbles burst sadly bubbles don't last forever they best because the water they are made of slowly evaporates the water tends to water vapor and mixes with the air as the water evaporates the skin gets thinner and thinner until it breaks and drive warm weather evaporation is quicker so bubbles don't last long well that explains it a lot so I think this one will be more successful


[887.0]
so now we've learnt a little bit more about the science part of blowing bubbles I think it's time to have a little more fun


[905.05]
war so now we finish the normal bubbles we are going to make a massive bubble but to do that we are going to need to make a mega bubble one so how we make that is we're going to get our long long piece of string and we're going to one at the end through our ring that's going to fold to the bottom of our loop and here he's going to need to be side by side here I'm going to loop it around your fingers and knot it necklace so the lot is there and your ring is at the bottom of your loop so if I stepped here we've got our step one finished and we're going to get one piece of string from the whole loop and about 50 centimeters down so about here we're going to use one of the bubble Stoppers we're going to put it through the little hole and then please over the big hole so then when you pull or become a loop it and you need to repeat this step a tiny bit further down so say about here and we're going to repeat that step by putting it through there pull the ball and round the big loop and put for step three we're going to get our long chips and we're going to stick them in the big hole so just like this you're going to repeat that step with your other tube onto the other bubble cutter so that's this looks like I finished all my steps and we've completed our mega bubble on so the only thing left to do is to make our mega bubble but doesn't look like we have room to do it in here I think we've got to go outside


[1037.549]
so you've had a lot of fun with these pebbles but have we actually thought about the science behind it you might have noticed when we were playing with the bubbles today that they had little sheets of colors flowing through them this is because the light bounces off the inside and the outside of the bubble creating a rainbow effect you might notice that one way of blowing bubbles for this star shape they turned out a circles this happens because the bubble always tries to be the smallest that it can be this is a sphere shape also known as a circle when you blow into a bubble the molecules expand but due to surface tension when the bubble closes up all the molecules group together to make it a smaller shape it can be this is always a stronger shape it can be as well you will know when the bubble is about to burst when the colors disappear due to a fact where the skin on the bubble is very thin did you know that the world's and long lasting bubbles lasted for three hundred and forty-one days and that is nearly a year the world's biggest bubble was made in 2005 which was three cubic meters and which could have held three tons of water do you know any other bubble facts put it in the comments below I hope you enjoyed learning about bubbles with me today if you did like and subscribe to channel and I'll see you next time bye hi guys and welcome to another video today we are going to be doing some dry ice science both my first experiment I need my safety guards on as I'm going to be getting some dry ice into my bowl and pouring some hot water in and let's see what happens here we have our pot of dry ice still it into my into my bowl then I'm going to add my hot water let's see what happened whoa dry ice is carbon dioxide in a solid form it's usually in a gas form but to get it into a solid it has to be burns Oh minus 80 degrees Oh so cold let's play around with it


[1195.07]
you


[1204.55]
my next experiment I am going to makin some doody paint glow-in-the-dark bubbles so let's see what happens first I'm going to get my boiling hot water and then my UV paint we are going to mix that up and then with my safety glass and rain spent our dry ice see what happens


[1248.27]
you


[1262.89]
well that was amazing using the UV paint and the UV taught the dry ice glows for my next experiment I'm going to be making homemade ice cream delicious okay so first we're going to put our safety pants on and get off dry ice and then we're going to tip it into our big bag now I'm going to crush the ice using this beaker


[1309.73]
they're now going to pull this into my beeper


[1329.53]
and I'm going to add three parts double cream and one part milk suck tip pull the fish in and now we're going to use one pop milk


[1358.48]
and now we're going to stir it all together


[1371.21]
well it has exploded a bit but after a few minutes of new sterling it had turned into a beautiful homemade ice cream and I can't wait to have it later in my apple crumble for my next experiment I am going to be making a rocket so this we need a bottle a funnel a cup hot water and a fever of our dry ice so when I saved it up we're going to go


[1407.799]
before we go outside we are going to put our dry ice into our bottles to go to our funnel


[1417.659]
now let's take all of this outside for blast-off so now we're outside we're going to be doing all rocket experiments so the Falcons for our Washington and all the gas will come flying up


[1453.32]
for my next experiment we are going to making smoke Li to this we're going to need a cup which you cut a hole in bottom which we will need later on and we have our dry ice which grows tips in size of cutters okay and then we are going to need some cling film go over top very tightly


[1524.83]
and make sure and to make sure it's really tight we're going to put a few elastic bands around it and we might put a few layers on make sure it's really firm


[1547.62]
without filling in it the dryer should still be in the bottom of your cup and then you're going to get some water until it inside little Hollow and when that's happening you're going to flip to the bottom with a cling film and it'll smoke things should come out the top of your hollow steel


[1581.07]
that's so cool let's add some new water


[1600.01]
Nik ah


[1611.4]
so now we've done it with a big cup we're going to do it with this small cup and see if we can find it different


[1623.429]
my next experiment I'm going to making a massive bubble bonus we're going to have to soak our dish cloth in our washing up liquid solution we're going to get our dry ice with us safe eager


[1676.43]
important


[1688.22]
and then on the rim we're going to take our finger round with the washing-up liquid but make sure it doesn't go in your cheese


[1704.59]
you then our water well let it settle and then we'll try and make our bubbles


[1730.22]
every time I swipe my cloth across them it's a small bubble of carbon dioxide


[1750.71]
Wow look at it don't like blow it over shall I pop it yeah I think I should pop it I think I need a big finale thanks for watching today's video guys what excitement taught me to do next put it in the comments below please remember to Like and subscribe to channel and I'll see you next time
