DIY HOT Wheels Race Truck Powered by 2x CO2 Cartridges

In today's video I show you how to make wooden hot wheels truck powered by 2x CO2 cartridges. It got too much power, so as result the truck is quite unstable. Anyway, we get interesting race between 2017 race car model and 2018 truck. Who wins?
Also, we made automatic launchers for each car to let them start at the same time.
