Ever wondered what a blazing rocket looks like on the inside? In this wicked little video, workshop wizard Ben Krasnow describes how he designed a hybrid engine out of acrylic in order to observe the internal combustion of rocket propellant — from outside the rocket.

Some damn fine handiwork, if you ask us — even if this particular engine can only burn for ten seconds at a time.

Hat tip to Adam!
