Design is all about how products work. What an interesting way to understand the inner working of a product like a tattoo gun than seeing it preform under a slow motion camera. If you like tattoos this a must watch!!

I watched the video produced by Daniel Snyder on how to safely do the Coleman Slide which is a slide to reduce speed. The video had sections made in slow motion so that I could specifically understand what to do during the slide. I know a little bit about the Coleman Slide and I thought that this video clearly explained the steps. This video would be helpful for beginner longboarders because it is taped step by step. This was a useful resource because it taught me how to do the Coleman Slide. I have seen the Coleman Slide in videos but I have never practiced the move. I searched out this video because I wanted to learn how to do the slide. I liked the way this video explained the steps and I would search for other videos by this person in the future.I would recommend this site to other people because the video was very clear.

In this video professor Lewin does a great job of debunking common misconceptions of gravity (like the idea that heavy objects fall faster) with fun and intuitive experiments, It is a great introduction to physics concerning gravity.

In this video Professor Lewin thoroughly describes some of the simpler physics concepts of 1-d motion, If you have taken calculus you will probably be familiar with these concepts but it is still a good introduction to the format of Professor Lewin's videos, if you intend to watch more of them in the future.

In this video Professor Lewin does a great job of introducing some of the principles of rotation. He does several demonstrations of artificial gravity with a centrifuge and then with a bucket and rope. The video provides a great introduction to the mechanics of rotation.
