I (Adric), your humble blogposter have been collecting these ideas and demos and posting every year since 2011. And while I love fire and booms. It’s fun to try and scour the internet for ideas that don’t need big flames! Quelab is based in the middle of the Desert Southwest and fire danger is a real and growing thing in the western United States. So hopefully some of these ideas will help you wile away the long hours until its dark enough to see a public display, or before you responsibly do your and or your family/friends do your own small fireworks displays. Remember to always have a hose in the ready, and a bucket of water. Avoid setting off fireworks in weeds or near other flammable things.
Anyway on with the links! Keep scrolling down to see them all. As always, I did not write any of these. I’m linking you to the sources, Please mind your own limits and don’t injure yourself or others.
Drone dropping things.
Have a drone? Perhaps you can follow this instructable to allow it to fly over and drop glow sticks, led/battery “Throwies”, or perhaps some biodegradable confetti?
Bonus link, Cody’s Lab, Dropped a roll of TP from a drone.
Fun with Dayglow Dyed Yarn
Can you make firework images with this?
Bonus video, some dayglow dyes will actually glow in the dark for a moment, if you get them really cold.
Dollar Store Water Squirter Vacuum Powered Toy Cars.
Sound Resonance Powered Soda Bottle Rockets.
Ever blow across a bottle and hear a note? if you play that note, the bottle can puff out periodic directed jets of air, and if you balance them right you can get them to spin in a circle.
An Evaporagraph you can make!
An evaporagraph, is a way to use temperature to cause a dew like image on thin plastic.
Fun with dead Fluorescent tubes. AKA portable 8’ vacuum*
This one does involve ripping the cap off a fluorescent light tube and then breaking the small fill tube while the whole end is under water. are you surprised at how little gas there is in them? keep in mind there is a teeny bit of mercury in the gas, but as you can see it’s pretty teeny. *it would be best to when done, pour the water out and let it evaporate off just to avoid getting any mercury contaminated water into the water system.
Make Water Droplets Spin like a Teeny Firework
Making soot hydrophobic surfaces and some scratches on it, you can make water do a dance.
Making a Rainbow of Silver Nano Particles
This one may be beyond most home labs. But it is not super hard
Posters printed with pyro mixtures.
Well this one has some fire, in fact it’s pyrotechnics painted on paper, but surprisingly the paper in general does not burn, and leaves a image behind. Which I think is rather fun.
Small Popcorn Cannon, In the “Shut up and take my money” sort of thing.
I would love to have one of these. while this does need heat/flame, the boom is just from water flashing into steam!
Here is a list of links to previous years Fireless Fourth Links!
