Could you do this with dry corn starch? Shake it up in the bottle and light it before the dust settles.

- huhtenberg 2y agoI wonder if adding a static charge to the dust would help it to stay airborne longer.
- hermitcrab 2y agoI'm not sure that corn starch would stay as a fine powder long enough for that to work. However, if you have a long cardboard tube: * place the tube vertically with an ignition source at the bottom (small candle perhaps) * pour fine powder in the top (may need a step ladder if the tube is tall enough) * satisfying whoosh Don't look down the tube as you are doing it and don't do it indoors, obvs!
- pbhjpbhj 2y agoA common science demo in UK used to be exploding a cloud of custard powder - ostensibly powdered sugar and cornstarch. https://youtu.be/aGBT5pwxThU?si=ay9fm_ZaYImIeNK8 https://youtu.be/aGBT5pwxThU?si=ay9fm_ZaYImIeNK8 is similar to how it was done.
