For some reason popping bubble wrap is really fun. Similarly popping kernels of corn with a sun is also really fun. The object of Hotcorn is to pop as many kernels as required in a given amount of time. When I explain it it sounds like it would be boring, but when I explain popping bubble wrap also doesn't sell it. This is one of those games that you just have to play to see why it is fun.
