Make your very own spooky bouncy eyeball with this brilliant science kit. Pour the powder into the mould, place the mould into a cup of cold water and wait for 1 minute. Remove the mould from the water and let it rest for 5 minutes. Now you can open the mould and see your completed bouncy ball. Ideally wait for 60 minutes before playing as the ball will still be sticky for a while. Once you have made your Horror Lab Make Your Own Bouncy Eyeball why not use the remaining powder to create a multi coloured ball?
