In the mid-ninth century, Chinese chemists, hard at work on an immortality potion, instead invented gunpowder. They soon found that this highly inflammable powder was far from an elixir of life -- they put it to use in bombs against...

Fireworks combine chemical processes, from combustion to spectroscopy, to create spectacular displays. Discover what happens when the fuse is lit. Chemistry - Reactions - Learning Points. Fireworks involve combustion and exothermic...

In this video we make electric matches to safely detonate our experiments.

You should aim for a 95-5% ratio of your propellent to nitrocellulose (pingpong ba
l
ls).

A pingpong ball weighs 2g, so use about 50g of powder....

Matthew Tosh shows us the science behind firework displays which can't be performed in the classroom. In an explosive programme Matthew shows us his personal Top 10 demonstrations including flash powder mixes, Chinese firecrackers, gerbs...

We’re going to talk about how guns went from fireworks to 3D printed weapons. We’re going to talk about how technology development works, and whether or not “progress” is really a thing.

We made a cannon that fires water bottles. Why you ask? Why not!?!<b<br/>r/>

Using 1-2 ounces of blackpowder,<b<br/>r/> and 10-16oz of water.

If we filled the bottles up all the way they exploded!

Learn about the composition and functioning of firecrackers. Black powder inside the cardboard tube ignites when the fuse is lit, causing a chain reaction that leads to an explosion, flash of light, and loud bang. This video also...

This is our first attempt at exploding arrows, we probably used a half ounce of black powder in the arrow itself. It was a carbon arrow. We removed the tip and replaced it with a large shotgun primer.

I saw these first in the...
