Cardboard Marble Run
Professor O will help you learn: Gravity, slopes and speed - steeper ramps make the marble go faster.
⚠️ An adult should help cut the tubes with scissors. A marble is a choking hazard, so keep it away from children under 3.

Whoosh-Crackle-Pop Sound Effects Kit
Children make whooshes, crackles, pops and bangs from household junk to create a firework soundtrack. They learn that every sound is made by something vibrating, and think about why real fireworks can frighten pets and some people, and how to be kind on Bonfire Night.
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.
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.
