5 Crazy Science Stunts You Can’t Try At School


Grab your safety gear and sign the waiver,
because we’re exploring 5 insane science stunts you won’t be learning at school. Normally we don’t think of metals as being
very dangerous. We use them all the time, but sodium metal is one that’s extremely
reactive. The second it touches water, it starts ripping the water molecules apart and
releasing hydrogen gas, which you can see is highly flammable, and in some cases, explosive.
The vigorous reaction is exothermic, and gets so hot, it’ll spontaneously burst into flames,
and can explode. Now, if a piece of wood is thrown on top, the elemental sodium blasts back with
tremendous power, and sends the wood flying. Now the reaction also forms sodium hydroxide,
which is very caustic, and typically used as a drain cleaner. But you might remember
from a previous video, we can tame that dangerous chemical with bacon grease, and make it into
a custom bar of shower soap. For this next experiment we need a plastic
soda bottle filled a third of the way with lukewarm water, and a little bit of liquid
nitrogen. Now if we pour a bit of the cryogenic fluid into the bottle and simply turn it upside
down, the bottle blasts off with tremendous force. Now we’ve got a high risk, hand-held
rocket launcher. This works because the liquid nitrogen floats on the water and the gas can
escape out the top. But when the bottle is turned over, the liquids trade places, and
the nitrogen is instantly vaporized, blasting water out the nozzle with incredible pressure.
These bottles can shoot hundreds of feet at high velocity, which apparently is enough
power to break clean through my kitchen window. There’s also a risk of these blowing up
in your hand, so why don’t we move on to the next experiment while we’re still in
once piece. Now one way to super-charge a halloween party
is with a spellbinding blast-o-lantern. Just pour a bit of calcium carbide into a small
plastic cup, then carefully set it inside a pre-carved pumpkin. When all the pieces
of the pumpkin are back in place, simply pour in a bit of water, and put the lid back on
top. The pumpkin will slowly fill up with highly flammable acetylene gas. So as you
might be able to guess, we’re going to light that off with a fuse. Now when the spark hits
the gas, it blasts out, a sinister looking face, with a startling amount of power. Your
guests will probably find this trick extremely amusing, because anytime you mix oxyacetylene
gas with a pumpkin, it’s bound to get a very spirited reaction. With some simple engineering, you can turn
a junk microwave like this, into an electrical metal melter, that will pump out a shocking
800 amps, of metal melting current. We just need to break inside, to access the electronics,
then locate this awesome piece of equipment .. a 1500 watt microwave oven transformer.
Now there are 2 coils on this beast. A primary and a secondary, and if we cut off the secondary
and replace it with 2 gauge insulated cable, we’ve got ourselves an incredible device
that will melt metal in just a few seconds. When it gets turned on, it pumps out a staggering
amount of electrical current, which you can see is enough to reduce a machine screw, to
a flowing river of molten metal. It’ll also weld sheet metal, melt neodymium magnets,
and heat steel until it’s glowing hot, just in case you’re in the mood for a little
amateur blacksmithing. For this last experiment we’re making pie,
but trust me, you don’t want to eat this one. We’ll need to take this recipe outside
and away from anything flammable, and get started by mixing precise amounts of sugar
and potassium nitrate. This is a highly flammable mixture already, and the more we shake it,
the faster it’s going to react when we light it later on. Now if we warm this powder on
medium-low heat, you can see the sugar begins to caramelize and absorb the nitrate salts.
When it’s all melted and mixed together, it kind of looks like pumpkin pie filling,
so why don’t we try pouring it into a pie crust, and letting it set for a few minutes.
If it weren’t for the fuse sticking out of the center, you’d think it was just a
regular pumpkin pie. But watch what happens if we light it off. It bursts into a fountain
of flames and spews hot ash like a miniature volcano. This gives a whole new meaning to
the term “Pie”-rotechnics, and this just might be the first dessert, that burns it’s
own calories. Well there are 5 crazy science stunts you
probably won’t see in the classroom, and while I can’t recommend you actually try
these experiments, you know what would happen if you did. That’s it for now. If you liked
these projects perhaps you’ll like some of my others. Check them out at www.thekingofrandom.com Well, that was exciting. Hey guys, I hope you liked these demonstrations.
They are some of my favorites, probably because they’re a little bit dangerous, but that
keeps it real. And if you felt the power and learned something new, then why don’t you
share this video on Facebook, and Twitter, and reddit, because it really does help a
lot. Now there’s one thing I need you to do right
now. Click on this video that Alltime10s just released on their channel. It’s showing
10 Crazy Experiments that Scientists Did To Themselves. This is a video you need to see,
and if you don’t know who Alltime10s are by now, you need to. They do some of the best top 10’s videos
on the internet. They have a super popular YouTube channel, with almost 3,000,000 subscribers,
and as you might have guessed, this video is in collaboration with theirs. So go check
them out, subscribe to them, and tell them that Grant Thompson sent you. Now in the next couple of weeks I’m going
to show you how to make miniature rockets that will launch off your desktop, so subscribe
right now, if you haven’t already, because I’d really like to see you around in those
project videos. Are you still here? Go check out Alltime10s
