How do you use Ben 10 omnitrix?

The Omnitrix is a device from a Ben 10 cartoon. It is a watch-like device that lets Ben turn into aliens. While you wouldn't be able to make an Omnitrix that actually works, you would most definitely be able to make a pretend one. You can make one using construction paper, glue and tape, or you can go to a craft store and buy plastic watch pieces and assemble your own. If you want to save yourself the trouble, you can buy a toy Omnitrix at many large stores, such as Walmart or Target.
