Hacker Daily teaches you to how to make a rocket "outta trash". They take a bunch of everyday materials (paper towel roll, body spray cap, paper cup glue gun, scrap cardboard and a model rocket engine) and create a rocket, by first cutting cross hairs in the bottom of the cup and gluing the rocket engine inside. The video than tells you to insert the paper towel roll trough the bottom of the cup. Than they tell us to glue the body spray cup on top of the "rocket". After adding fins the rocket is ready for lift of. The video compares the lunch of a store bought rocket to the homemade one and shows the superiority of the recycled one.
