To use this Mattel Netflix Let's Race Action Set, first, set up the ultra - cool orange track and place the launcher at the starting point. Put one of the iconic cars on the launcher and give it a good push to start the race. You can use the Electric Tower to make the car jump over the bolt of electricity, or try the other three stunt options like launching through the flame, riding the loop, or doing a flip. When connecting this set to other Hot Wheels® track sets, make sure the tracks fit properly. As for maintenance, keep the cars and tracks clean by using a dry cloth to wipe off dust. Avoid getting the set wet, as it may damage the parts. Store the set in a dry place when not in use to prevent any wear and tear.
