A self-heating cushion which when triggered will keep you warm and comfortable
I was given a week to think up and create a range of inventions for Blue Peter viewers who have to wait in the cold for a bus. The inventions aim to tackle some of the most annoying problems faced at a drafty bus stop and showcase the design and prototyping process.
This idea uses the rechargeable self-heating packs you can buy in camping shops (and that I use in my self-heating crockery). The pack is placed in a soft neoprene cushion, and can be triggered when you are sat in the cold to provide you with a lovely heated seat.
