How to Do a Science Experiment w/ Bubbles | Science Projects


Everything on earth is made up of matter. Now matter is made up of three states and
it’s not New York, New Jersey, and Connecticut. I’m corny. But, three states, solids, and then you have
liquids, and then you have gases. Now it’s really easy to teach about a solid
because you see you can hold the solid. Solids tend to keep their shape and the only
way you can change the shape is by using the force. Think of an apple, if you bite into you can
change its shape. Then you have a liquid. Liquids flow, you can hold the liquid, and
liquids will take the shape of whatever container you put it into. Now think about air, think about gases. How hard is it for a teacher like me to teach
a kid like you about something that you just can’t see, right? It doesn’t really have a shape, or a size,
right? How do I tell you that it exists? Well, what I like to do is to create a really,
really cool solution that I kind of like to as “Bubble-ology”. Your rule, everybody loves bubbles. If you’re in the bathtub and I love to take
bubble baths, that’s why my skin is so smooth. But, think about it, you play with bubbles
in the bath, right? Or if you fart in the bath you make a giant
fart bubble. That’s not that bad until the fart hits the
top of the water and then it smells. That’s a little disgusting. But you don’t want to do those types of bubbles. But, right now, all I’m going to need is water,
and then you’re going to have use some of your parent’s dishwashing soap, okay? Keep it a secret. But it has to be dishwashing soap. Not shampoo, not body wash, dishwashing soap. And I’m going to show you what I’m going to
do. First, cup. I love, you see science and math go hand and
hand, okay? I’m going to measure four cups of water. So you guys can count with me. One cup, two cups, that’s three cups, and
that is my fourth cup. And I’m going to use half a cup of dishwashing
soap. Just like this. I apologize, it does look like someone’s going
to the bathroom, a little gross. And I’m going to pour this into my container,
just like that. And I created a mixture. A soapy water mixture. Now, I have a cool little secret for you guys,
okay? If you do not have my next chemical, you do
not need to use it. But, when you go to the store, to the toy
store, and buy that special bubble solution, the reason why those bubbles do not pop as
fast is because they’re using a special ingredient that you can get at any pharmacy. It’s not that expensive. It’s called glycerin. Glycerin will cause your bubble not to evaporate. You see? Bubbles are made out of water. When the sun heats up the water think about
if you have a spill on the floor, right? The spill is there. You go out to play. You come back. Is the water still on that floor? No it’s not. What happened to it? It evaporated. It turned into a gas that’s all around you. Well, by adding glycerin it causes the bubble,
see bubbles have skin, their skin is not like our skin, it’s extremely elastic. It can stretch and stretch and stretch. I can take the smallest bubble, I can turn
it into a bubble the size of this room. Bubbles have amazing properties. But now, by me adding this glycerin it causes
my bubble not to evaporate as fast. Remember, evaporate is when liquids turn into
gases, okay? So, I’m going to put one teaspoon of glycerin
and again you don’t need to do this, it’ll still work without it. So you don’t have to be upset. You all have dishwashing soap because hopefully
you wash your dishes. And you all have water. This will just cause it not to evaporate as
fast. And I’m just going to put four of these in. And then I’m going to stir it around. And now I have created an amazing bubble solution. Now some of you are going to say to me ‛Carmelo,
what does this have to do with how we started? You started talking about matter.’ And I told you that matter takes up space. And I said that there were three states of
matter, right? Solids, liquids, and gases. And I then said how hard is it to show you
that gases take up space? Well, I can show you now. Check this out. All I need now is a straw. Now some of you are going to be like, ‛oh
man, this is boring. The dude’s going to blow bubbles in the air. I’ve been blowing bubbles since I’m two.’ But wait, we’re going to do this with a twist. Take your straw. First I do need to show you something because
if you dip the straw in and you take the straw out and you blow hard, you kill the bubble
already. It didn’t have a chance to become a bubble. The bubbles dead. You want to blow slow. Now, you have a force of air. Your lungs are your source of your air. So when you dip your straw in and you take
your straw out, it sounds like the Hokey Pokey. Dip your straw in and you take your straw
out and you do, no, all right. Dip it in. Take it out and blow slow. And it pops. Actually, it evaporated. Did you see the more air I put the bubble
got bigger. This is proof that air and gas does take up
space. But how about this? I said we’re going to do it with a twist. Bubbles have an enemy. It hates things that are dry. If a bubble touches something dry, the bubble
will go bye-bye. But if you wet anything, you can make a bubble
on anything because bubbles love things that are wet and they won’t be upset. But remember if it touches something dry it
will go bye-bye. If you don’t believe me, check this out. See my table? It’s dry. Everybody blows bubbles into the air. You could blow a bubble on anything. But if you blow it, it popped, right? The tables dry, bubble goes bye-bye. But watch this. If I wet the table. Little spray. I’m going to wet the surface of the table. The more the tables wet, the bigger I can
get my bubble. But the moment that bubble touches a dry spot
on that table, that bubble will pop. Now believe it or not, I can make a bubble
the size of this entire table. I just need to put more what? Gas. The more gas, the more space. I put gas, the more space. This is proof that gases take up space. It’s just so cool how we can use bubbles in
water to illustrate that air takes up space. Dip your straw in, take your straw out, and
now observe the master. Check this out. I’m going to keep blowing until it pops. Look at that. Think about how small the bubble skin was
inside the straw. It evaporated. Now once it evaporates, you know what’s
cool? It leaves a perfect circle on your table. Take a ruler and you can do like a bubble
Olympics. Challenge yourself or challenge your friends. Measure the diameter of your bubble. And you can be like, ‘Wow. That was eight inches.’ Well now try to make it ten inches. And you want to see something even cooler? Check this out. What happens if you touch a bubble? The bubbles going to pop, right? Watch this. Make a bubble, now if I touch it with the
dry part of the straw that’s not wet, bubble pops. But I could actually cut a bubble with a knife
or with a straw or with a scissor, as long as it’s wet. Check this out. Make a bubble, wet my straw. Sha, boing, boing, boing, boing, boing. Doing, doing, doing, doing, doing. Look. I can cut it. The bubble doesn’t pop. But the minute you touch it with something
dry, bubble pops. Saw that? And want to see something even cooler? I’m able to put my straw in the bubble. See this is all about what science is. It’s about asking questions. Ask a question and then you make a prediction
and then you test your predication to see what happens. Well if I’m able to put my straw in a bubble,
what happens if I blow another bubble in a bubble? That’s the question. Now my prediction is, maybe the bubble will
get bigger. Now I’m going to test it. That’s the process. I’m going to do it now. So let’s see. I’m going to make a bubble. Now I’m going to make a bubble or see what
happens if I dip this back in my solution, what happens if I blow another bubble in a
bubble? I just made a bubble inside of a bubble. Could I make a bubble in a bubble in a bubble? And blow. Can I make a bubble in a bubble in a bubble
in a bubble? Oh my gosh. Now you can ask another question. What happens if I touch the outside bubble? Make a prediction, test it. Pop, pop, pop. Look at the baby bubble. Wait, do you think I could pick up that bubble
if my hands are dry? Probably not. What if my hands wet? Could I pick up a bubble? I got him. Think about how much fun you can have. We can prove that air takes up space and just
have so much fun using nothing but soap and water. And that’s my Bubble-ology experiment.
