Auto racing is an expensive and technically complex hobby, but it can be just as fun when it's scaled down to where the car can fit in your hand. CO2 dragster racing lets you do just that -- build a tiny racecar that can move at incredible speeds and incorporates many of the same principles as full-sized, real cars do. It also puts your knowledge of science to the test. Think you have what it takes to build a CO2 dragster? Let's find out!
