Celebrate the new year with some home-made pyrotechnics!

I’ve made saltpeter/sugar smoke bombs before, and they’re a lot of fun. I haven’t tried with baking soda and crayons, though.

I used a campstove outside to “cook” the bombs, in case the mixture ignited, and wrapped them in cupcake-sized tinfoil disks with a bunch of matcheads.

Without colour, the smoke burns white and the fire is purple.

Try not to breathe the smoke and don’t die.
