This National STEM Centre DIY Wave Machine demo is a perfect hands-on experiment for home or in the classroom. The ingredients: Duct tape, wooden kebab skewers, and jelly babies, (or dots… or maybe gummy bears if they’re heavy enough). Watch as science teacher and sci-comm filmmaker Alom Shaha lifts up or pushes down on any jelly baby in this precisely-made apparatus.
Also, check out the Candy Wave Machine that physics teacher Frank Noschese made with his class. Pro-tips included.
