The creative zone is where you can stimulate your artistic side by painting your own canvas* and designing your own t-shirt*, and you can also have lots of fun drawing, gluing and getting messy.

The Royal Gunpowder Mills has a Rocket Vault with guides who were rocket scientists when the site was a top secret research centre, so it’s only right we delve into rockets in the Test Zone where you can Make and launch your very own Air Powered Rocket, Blast off Rail Rockets and create your own bespoke Rocket using whacky materials!
