  • What's up everybody! Welcome back to my laboratory,

  • where safety is number one priority.

  • And today I'm going to show you

  • 5 Science Experiments you can try at home.

  • Let's check this out!

  • For this science experiment, we're going to need a potato and a straw.

  • First, we're going to grab our potato like this and try to smash it.

  • You see.. straw.. just breaks

  • It does not go through the potato at all.

  • But if you grab different straw and hold the top of it, let's see what happens.

  • Yeah, you see it went through all the way.

  • So "straw through the potato," it's because I was holding the top of it.

  • It goes through it, much more sturdier. Let's try this again, this is too much fun.

  • Boom! You see?

  • "Straw through the potato," pretty cool trick and science experiment.

  • Awesome huh?! But if you're not closing the top of it,

  • you see it does not break all the way through.

  • Now close the top.

  • All the way through.

  • This is so much fun, I can do this all day!

  • "Straw through the potato" trick, science experiment. Let's get to the next one.

  • For this experiment, we're going to need a coin and a balloon and I got a see-through balloon because

  • we want to see the coin inside our balloon.

  • This experiment is called "Spinning coin in a balloon".

  • [Blows Balloon]

  • We're gonna blow the balloon up,

  • and you see there is the coin in there right now.

  • [Coin spinning noise]

  • Do you hear the-

  • the coin making noises?

  • [Coin spinning noise]

  • And it's spinning circles like crazy! How cool is that?!

  • [Coin spinning noise]

  • Look at this making circles, without falling. How cool is that?

  • [Coin spinning noise]

  • Pretty cool experiment, isn't it?

  • [Coin spinning noise]

  • I like how it's spinning on the walls and not falling.

  • [Coin spinning noise]

  • [Coin falling noise]

  • Till it loses its inertia and falls down.

  • For this experiment, we got water in a beaker and Gelli Baff.

  • Step 1 and step 2, let's see what it does. This is pretty cool!

  • Aww man.. spilled most of it.

  • Now let's pour some in the water and mix it,

  • and let's see what happens.

  • Pour a little bit more...

  • [Stirring noise]

  • Wow! This is so cool, oh my gosh.

  • This has turned into complete gel, look at this.

  • Wow! I might have put a little bit too much.

  • [moves beaker noise]

  • Awesome.

  • Now we got Gelli Baff step 2. Let's see what it does at step 2.

  • Pour some of that and keep- start mixing it.

  • Maybe pour some more..?

  • Wow! look it's turning back into the water! This is insane!

  • How's this possible?

  • [Stirring noise]

  • Pour some more of this, step 2.

  • Secret ing- ingredient

  • Let's see if to turns back into the water completely.

  • [Stirring noise]

  • Look at this, step 2 almost completely turned the jello into the water.

  • Pretty crazy!

  • So it feels we made this jello from water, and then step 2 it turned it back into the water.

  • Pretty insane experiment.

  • I like this a lot! Look at this, this is just water now.

  • Most of it anyways.

  • Pretty cool, huh? Look at it, it's just water now.

  • For this science trick, I got here two giant steel balls.

  • Not giant, but pretty big never-the-less.

  • Look how big they are, and they are solid.

  • [Smashing two giant steel balls]

  • You hear that? They are very solid steel balls.

  • So what we are going to do, grab a piece of paper fold it together.

  • BOOM!

  • Unfold it, and stand it up like this,

  • and then what we are going to do is grab this two balls and smash it against each other, like this.

  • And we'll see what happens.

  • It burned through the hole and it smells like fire. So awesome!

  • Pretty cool experiment, why does it do this? Why does it burn through the hole?

  • What does the two balls do?

  • To burn off a hole right in it and it really smells like fire.

  • It smells like burnt paper.

  • How does this work? Let me know in the comments below

  • For this experiment, I got Wacky Hall Walker or a Spool Tractor,

  • whatever you call this experiment. So it comes like this

  • We gonna open it up.

  • So what are we going to do, is just grab one lid,

  • and stick through this rubber band, just like this,

  • and it from this side. And then we're going to grab paper clip and put it through like this,

  • And then it comes with this little hook, so we can hook up the rubber band.

  • BOOM!

  • I guess it makes it easier, to put it through this little cap as well.

  • Then we're going to put washer in here, on our rubber band after the lid,

  • And then I'm supposed to put bead on here. And the last we just need a pencil.

  • And now all I had- need to do is just surro- turn it around just like this.

  • We're gonna spin it up, a lot.

  • Now all I have to do is set it on the floor, and its just gonna take off.

  • Pretty cool huh?!

  • You can do it from the jar easily.

  • It keeps going, and the more spins I'm gonna do with the pencil,

  • the faster it's gonna go, just don't do it too tight so the rubber band doesn't break.

  • Pretty cool huh?!

What's up everybody! Welcome back to my laboratory,
