Isabella and Riley from Canmore, Alberta present their “Compawst Bin” a rugged compost bin designed to keep bears out. Connor and Spencer from Sudbury, Ontario present their new “Biodegradable Plastic.” They hope their invention will help reduce the number of plastic grocery bags in landfill sites. Riley and Isabella lead Team Edison against Spencer, Connor and Team Einstein in the Invent-Off Challenge to see who can create the best Pet Habitat. But first, each team must compete to build a UFO in the mini challenge. The team that builds the UFO that stays in the air the longest wins an advantage for the big Invent Off. The Genius Cup is at stake! Which pair of inventors will lead their team to victory in the Pet Habitat Invent-Off and take the prize?
