When you don't have a paddle or a table what can you do with a ping pong ball? Well you grab a sharpie marker, a craft knife and a battery operated tealight and you make yourself a Jack o' lantern.
Use the sharpie marker to draw a face on the ping pong ball and then with the craft knife, carefully cut an x on the bottom of the ball. Cut away just enough of the plastic so that the ball will fit over the tealight flame. This is not my original idea. I saw several of these online. I haven't been able to get myself in to crafting mode but this was quick and easy. After I took this picture I also poked a hole in the top and stuck in a green pipe cleaner for a stem.
