The summer’s almost here, and what goes perfect with scorching heat and unbearable humidity? That’s right, fire and explosions. But skip the fireworks and BBQs this year, and instead make your own rainbow pyrotechnics show with materials you can probably find in a hardware shop.
Surprisingly, making blue, green, or red coloured flames doesn’t require a PhD in chemistry—just tinted lamp fuel which isn’t that hard to come by. Add in a generic spray bottle, an open flame, and you’re all set for a memorable firework extravaganza. The high-speed camera is optional, but certainly results in some memorable footage [YouTube]
