In this video, I will show you how to perform the color-changing, blue bottle experiment with common household products.

In this guide, you'll learn how to make your own boric acid from borax and other common chemicals to produce a green flame when mixed with methanol.

This slime is toxic-free and can be used as either a kid toy or to make a great prank. This slime can be made in just a few minutes and doesn't require much for materials. Our video explains in detail how to accomplish this project with step-by-step instructions.

In this video tutorial, you will learn how to use sparklers, or fireworks underwater. You'll need some sparklers, tape, glass container, a lighter, and, of course—water.

For Chemistry, but my professor said to only experiment with things related to eco or bio stuff. Help?

In this Quick Clip, I'll be showing you how a supercooled soda is transformed into a slushy "slurpee" in under 4 seconds. I was inspired to do this little soda trick by The Super Effect's video on YouTube from a few years ago.

In one of my previous articles, I showed off how to make water freeze into ice instantaneously. In this article, I'd like to elaborate on this, and show how a glass of water can turn to ice instantly on command. What exactly is this supernatural power? Discover the secrets to ice-bending—in real life.

Sure it's been done before, but it never gets old. There's something magical about dry ice, bubbles, and especially the result you see when they're combined!

How heavy is a plastic bag? Not very heavy at all, but in order to use a plastic bag to help me karate chop a thin wooden stick, I don't need weight—I need air pressure. Below, the "Quick Clip" demonstrates the power of air pressure via the vacuum created between a plastic bag and the countertop.

Have you ever seen water freeze instantly? This "Quick Clip" shows some of my personal experiences with making instant ice using a bottle of water supercooled in a freezer.

i tried making hot ice numerous times with sodium acetate tech anhydrous and failed. plzzzzzzzzzzz help!! can u give me exact measurements and directions on how to?

A lot of my hacks use salvaged parts from an old microwave, with the microwave oven transformer (MOT) being the most useful component.

This science experiment deals with sublimation of dry ice into carbon dioxide (CO2) gas. In the video, I'll demonstrate how pushing a quarter into a block of dry ice makes the quarter scream and shake vigorously.

Wired Science teaches you the science behind glow sticks by showing you how you can make your own with chemicals that you can obtain.

Sound waves are a lot more versatile than you'd think. For starters, you can use them to project images onto a bubble and liquefy gummy bears. And now, YouTube scientist and optical illusionist extraordinaire Brusspup shows how sound waves can also be used to manipulate a stream of water into a zigzag shape.

Ice in placed on a sealed FLASK and the water inside starts to boil.

I am wanting to do some extraction from plants using acidic anhydride and would rather make it than buy it.

If you've ever lived in an area that gets ridiculously cold during the winter, you know that it's not so much like this...

Learn how to make your own slime with ingredients you can find around the house. It can even glow under a blacklight!

Helloo... New here

You can do all kinds of unexpected things with milk, like make your own pore strips and invisible ink, or even get rid of red wine stains with it. But did you know that you can also use it to make your own glue?

I SAY I LOVE SCIENCE BECAUSE WHEN I WAS 3 I MY MOM BOUGHT ME A TELESCOPE

Have you ever wondered what your DNA looks like? You have probably heard that DNA is a double helix, which is a pair of parallel helices intertwined about a common axis, but how do we know that? How can people look at DNA?

There's a broken canister of mutant ooze leaking down into the sewers! But don't worry because this sticky slime is non-toxic, and it's so easy to make, a three-year-old can do it!

First, we need the wood. Timber should be made ??of soft rock. Engaged in the manufacture of coal preferably in the spring because the wood at this time of the year has the least amount of salt and therefore it is a more quality coal. Softwood is alder buckthorn. Next we have to chop our wood into small pegs. The further process is shown in the video. All good luck :)

Glowing substances have always held a powerful appeal to people, and making new ones can be a lucrative business. If you need some glow powder for a project of yours, watch this video to learn how to make DIY glow-in-the-dark powder out of normal household chemicals.

Did you know that the average cost to make a penny is about 2.4 cents?!?

We've shown you how to make water change color on command, but how about just half of it? What if I told you that you can split a solution right down the middle and make the color disappear from one side, just by shining light on it?

Try out this science experiment... demonstrate pressure and volume. Watch this video tutorial to learn how to create an explosion with liquid nitrogen and a plastic bottle. See the demonstration of the exploding reaction of the pressure build up in the bottle.

What would happen if you stick your hand in a pool of liquid nitrogen? Would your hand freeze to death? Would it harden to an unnatural state? Would it shatter as soon as you touched something? Well, real life isn't like the movies (i.e. Demolition Man), so believe it or not, your hand would be safe, thanks to a little known phenomenon called the Leidenfrost effect.

Want to make boring old colorless water brighten up on command? Well, you can control the color of water with this little magic trick. Actually, it's not really magic, but a classic science experiment known commonly as the iodine clock reaction, which uses the reactions between water and chemicals to instantly colorize water, seemingly by command. You can use different colorless chemicals to produce different colors, and you can even make the color vanish to make the water clear again.

I cannot recover gold back from my Aqua regia solution. Can anyone help guide me on which chemical to use for recoering gold from computer parts dissolved in Aqua Regia solution.

Got an upset stomach or a little heartburn? America's favorite pink pill will cure it right up. But did you know that there's actually metal hiding in those chewable Pepto-Bismol tablets? Yes, metal.

If you're a Breaking Bad junkie who can't wait for the next episode, satisfy your craving with a little at-home chemistry and make some blue DIY smash-glow crystals!

A spectrometer is a device that splits light into all of the different colors it's composed of that can't be seen with the naked eye. It does this by using a prism to refract or bend the light.

It's been proven over and over that you can make batteries out of fruits and vegetables such as lemons, potatoes, and even apples. Turns out, passion fruit is also acidic enough to power a battery, but Maui Makers member Ryan K decided to take it a step further by adding a laser.
