Backyard Science

This episode opens with a DIY rocket experiment ("Ultimate Rocket"), followed by exploring how coat-hangers can be arranged to create bell-ringing sounds ("Bell Ringing Coat Hangers"), and ends with a look at how ropes tangle (and what causes "rope tangle") in everyday settings.

Here the show examines survival science by imagining being marooned without proper shelter ("Marooned Without Shelter"), investigates a "sound you can see" phenomenon (likely demonstrating sound waves or resonance) and explores how books can "fight" (maybe via balancing, physics of stacks or collisions) in "Fighting Books".

This episode guides you to make a homemade lava lamp effect, explores mould growth (as suggested by mould being mentioned in nearby episode titles) and investigates sweaty-cooling or "hot-sweat" phenomena.

Focus is on making an "oil sleeve" (likely an experiment involving oil and water or layering fluids), then balancing an egg on your forehead ("balancing an egg"), and comparing diet vs regular soda ("how to tell the difference between diet and regular soda").

A trio of segments: one about disasters at birthday events ("Birthday Disaster"), one on staying cool (evaporation, heat loss) ("Keep Your Cool"), and fun science tricks to "Impress Your Friends".

Explores how to get into a lollies (candy) jar efficiently ("Attacking the Lolly Jar"), the science of holding onto your money (perhaps magnets, static, coins) ("Hang on to Your Money"), and something about "Big Ears" (amplification, hearing, sound funnels).
