This cool RC hot rod is all about big, big sound effects (using a giant 4 inch amp’d up speaker) and a burning tire rubber gag that is really cool. Tires spin…screeching SFX…and then as the car gets traction…we see burning rubber tracks on the pavement. How do we do it? A pump sprays water on absorbent tires and then this water is transferred to the pavement as the car roars down the road. Very cool!
