Stomp-Powered Firework Rocket Launcher
Professor O will help you learn: Engineers a launcher from a plastic bottle and an old piece of hose that fires paper rockets with a stamp of the foot. Children learn that squashing the bottle pushes air through the hose at high pressure, and they investigate how launch angle and rocket weight change how far a rocket flies.
⚠️ Launch outdoors in an open space and never aim rockets at people, pets or windows. Wear safety glasses. Only one person stomps at a time and everyone else stands behind the launcher. An adult should use scissors or a knife if the hose needs cutting.
Steps
- Push one end of the hose into the neck of the bottle and wrap strong tape tightly around the join so no air can escape.
- Wrap a sheet of paper around the other end of the hose so it fits snugly but can slide off, and tape it into a tube.

Glowing Tissue-Flame Bonfire
Builds a pretend bonfire from cardboard-tube logs and tissue-paper flames that glows with a battery tea light. Along the way children learn that a real fire needs fuel, heat and air, and the Bonfire Night safety rules: grown-ups light fires, and everyone else stays well back.
Shake-and-Burst Firework Bottle
A calming sensory bottle where glitter and star sequins burst and swirl like fireworks, then slowly drift down. Young children explore how glue makes water thicker so things sink more slowly, and it is a gentle way to talk about loud fireworks if they feel worried on Bonfire Night.
Tube-Stamp Firework Prints
Turns old cardboard tubes into fringed stamps that print bursting fireworks on black paper. Children discover radial patterns that spread out from a centre, and see how bright colours stand out best against a dark background, just like real fireworks in the night sky.
