"if rocks don't work, maybe the wheels from my coworker's chair will" - Sun Tzu, The Art of War. In this video I make a homemade slingshot that lobs books, rocks, office chair wheels - whatever you can fit in the cart. It kinda sucks but it was fun to make and go throw things at a wall. Also, I answer the age old question: can you really throw a book through the wall? Well, sorta. Thanks for watching. Another engineering project brought you by yours truly. I like building things and seeing if they work.
