I feel flippy?

Today I remembered something I like to do when I am bored. I would do the water bottle flip challenge. It is where you fill up a water bottle about 3/8s of the way. Then you grab it by the cap and flip it up. The goal is to get it to land on the bottom and stand up. I wasn't very successful because I hadn't done it in ages. But I still did pretty well. I tried to flip it up the stairs and down the stairs except for the fact that I was very unsuccessful. My dad tried it as well and he didn't get a single on to stay up. Maybe I could do this as my newly learned skill. (rhetorical question)
