Wow in the World

In this high-speed episode of Wow in the World, Mindy and Guy Raz turbocharge an ordinary day… It’s the 25th-Annual DIY Homemade Go-Kart Derby! But in classic Mindy fashion, she isn’t showing up with just any homemade kart—she’s built a cutting-edge Formula 1-style race car! As it turns out, Formula 1 racing is basically “one giant science fair,” powered by teams of scientists working to design the fastest cars possible!Of course, getting to the race is no simple task. Instead of driving, Mindy insists on preserving the precious engine by enlisting the sleigh cats’ help to pull the car. At the track, they meet their driver– a familiar and unlikely face– and prepare for the big race. As the countdown begins, excitement builds, blending science, silliness, and speed into a wildly entertaining race-day finale!Packed with humor, wild antics, and fascinating STEM concepts, this episode shows how science fuels everything from backyard projects to the fastest cars on Earth.📺 You can watch the WOW of this episode right now on our YouTube channel, WowTube!
