Hot Wheels Rev 'n Launch Challenge Pack Review Unbox

This is an unsponsored video review of the Hot Wheels Rev 'n Launch Challenge Pack we purchased. It is part of the Hot Wheels Track Builder Series for ages 6-12. Watch us discover how it works and what damage it causes! We also use our Race Timer and Speed Measurer project to measure the speed of the car exiting the launcher. (See Cooks Projects TH-cam Channel • Race Start Finish Line... or below for details on how you can make this HotWheels Race Timer project.)
The Rev 'n Launch pack certainly gives the cars a big boost of energy - perhaps too much! BE CAREFUL - The cars are travelling extremely fast and will damage people or furniture that may be in the way.

A detailed instruction booklet for the Hot Wheels compatible Race Timer/Speed Measurer project providing technical drawings of the casing, more detailed instructions and hints on how to build the Speed Measurer project as well as the limited release source code for the Race Timer and Speed Measurer functions is available at:
