On your marks... Get set... Go! A race track like no other that shows how bubbles are tensile and elastic. Can you make a longer track or one with more bubbles? What happens?

To make your own you need: hooks, string and a piece of wood. Don't have those? No problem - a bunch of items can be recycled into a bubble racetrack. I've used rubber bands, cotton, nails, pins and even a cardboard base.
