Hydrogen and Oxygen Experiments
Show combustion of hydrogen without explosion. Light up the end of the hydrogen cylinder—should be metallic tube at the end. Contrast to oxygen—glowing splint ignites, but the oxygen itself doesn’t burn.
Show explosion of hydrogen with coke bottle filled in 2:1 ratio hydrogen to oxygen.
Show delayed explosion: pure hydrogen fills 2 liter flask with hole on the bottom. Hydrogen burns quietly as air enters the bottom forming explosive mixture which eventually explodes.
