How to Rip Stick a Skateboard

I knew how to do some tricks, but not many. I had a friend who got really good at skateboarding. So I made these videos for him filming these cool tricks that he did. And it was really impressive to see what things he could do with a skateboard. He was able to jump off high stairs and high platforms and land on his board on the ground. It was pretty cool. In English, when we say that something propels something else, this means that it makes the thing go forward. That's a compilation. These are tricks.
