I saw this idea on many Youtube channels: Take some steel wool, place it in a whisk, hook it up to a dog leash and light it on fire. Yes this was dangerous, please don't try it unless you have a garden hose hooked up and ready to go!
(I set the grass on fire more then once!)
I really wish this one had turned out! unfortunately the camera didn't focus when I started to spin the burning wool, I will most definitely have to try this again!
