Here are 5 cool experiments, you can try at home, part 1.

Look what you can do with a bit of water, and an empty glass bottle. If we put this

in the microwave on high power for 1 minute and 30 seconds, the water starts vaporizing

into steam. And of course that means the bottle’s going to get really really hot. So before

we touch it, we’ll need some insulated oven mitts. Now what do you think will happen if

we turn the bottle upside, down and dip it in a bath of cold water? The water gets sucked

up with a tremendous amount of force. Which, apparently can fill the bottle in less than

a second. This works because steam takes up a lot more space than water, so when it rapidly

contracts inside the bottle, the outside air pressure forces the water in to fill the void,

until the pressures equalize. Did you know you can turn a stack of pennies into a battery,

that will light LEDs and power a calculator? If we use sand paper to shave off one side

of the pennies, we end up with bi-metallic discs that are copper on one side, and zinc

on the other. Try stacking the pennies 10 high so they’re all facing the same direction,

then place pieces of cardboard, soaked in vinegar, between each coin. This makes an

improvised 6 volt battery with just enough power to light a couple of LEDs. The copper

top is the positive, the zinc is the negative, and surprisingly, 3 pennies is all it takes

to power a small calculator like this. That’s the power in your pocket change. This slick

little trick is good to know, if “urine” trouble. It might sound weird, but there is

a way you can start a fire with your pee. Pour some of the yellow liquid into a clear

plastic bag or plastic wrap, then collect the corners together and twist it around until

it bulges out to form a liquid sphere. Now you can focus the sunlight, and start burning

dark paper or fine tinder just like you would with a magnifying glass. Nurse the embers

into a flame with the help of some kindling, and you’ve just started a fire with your

pee. Did you know you can turn a hunk of butter, into a candle? Start by cutting a block of

butter in half, then roll up a bit of tissue paper to make an improvised wick. Push the

wick into the butter and light it, and incredibly, the butter burns just like a candle. Each

half gives up to 4 hours of light, so try it for yourself and see if anyone else finds

your experiment, enlightening. If you promise to be careful, you can make a mini pyrotechnic

display with some cheap disposable lighters. By hacking into the valve tensioner, and adjusting

it counter-clockwise 2-3 times, we can get it to shoot a flame up to 12 inches long!

It’s a micro handheld flamethrower that shoots clean-burning gas. Just don’t run

it very long or it might catch the casing on fire and blow up. You can also try wrapping

the spring around the flint to make a tiny flint bomb. Hold it in an open flame until

it starts glowing red-hot, then throw it on the concrete, far away from anything that

could catch on fire.  Well there are 5 cool

experiments you can try at home. Just make sure to use common sense and try not to get

anyone hurt in the process. That’s it for now. If you liked these experiments, perhaps

you’ll like some of my others. Check them out at www.thekingofrandom.com

I saved the best project for last. Hey guys. One of the best projects you can invest in,

is yourself. And you’ll get the best results by using the best tools. This week I’ve

been reading this book called the success principles by Jack Canfield, and it’s basically

an instruction book that will show you step by step, how to map out where you are in life,

to where you want to be, and show you how to make it happen. And because you’re supporting

my videos, Audible.com has sponsored me once again, which means I get to give you the audiobook

of your choice, free of charge. On their website it’s normally $23 to download, but if you

go through my link in the description, and sign up for their 30 day free trial, you can

get this book today for no cost. Now if you don’t feel this recommendation was right

for you, they have 150,000 other audiobooks you can choose from, or trade for, with no

questions asked. You can also cancel anytime with no obligation. So if you want to grow

a popular YouTube channel, or start a successful business, or even just ask that cute girl

out on a date, this book will give you the power to make that happen. And I really believe

that because these are principles I’m experimenting with all the time. Thank you for supporting

my videos, and I’ll see you in the next one. Bye.
