I went camping with my father in law, we had a few beers and then I secretly threw in a few packs. The flames were bright blue, green, red and even purple. My father in law started asking if I could see the colored flames, I asked him how many beers he had had. Great prank and a great way to enjoy a campfire.

This is easy to use and multiple items can be plugged in at the same time. Simply push the button to switch to another country. I recently traveled to the EU, Canada and Morocco and had no issues!
