Light experiments during the Science Show at OIST Science Festival 2025

Two photos from the Science Show. Left: An upside-down water dispenser bottle is filled with blue fire, dramatically spewing out a long flame at the top against a pitch-black backdrop. Right: The face of researcher Jack Featherstone is lit up with a bright orange flame held in the palm of his extended right hand without burning him, his left hand holding a long lighter.

Different chemicals produce light at different wavelengths when burned. On the left, a water dispenser bottle with ethanol burns blue when ignited, and on the right, PhD student and Science Show presenter Jack Featherstone ignites a bubble filled with propane in his hand. Note: Do not try these dangerous experiments at home!
