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 at the hardware store.
Surprisingly, making blue, green, or red colored flames doesn’t require a PhD in chemistry—just tinted tiki lamp fuel which isn’t that hard to come by. (If Walmart carries it, it can’t be that exotic.) Add in a generic spray bottle, an open flame, and you’re all set for a memorable Fourth of July extravaganza. The high-speed camera is optional, but certainly results in some memorable footage.
