We have held a piranha down down in the pantanal. How do you keep your fingers out of their mouth? Cheaters run about 70 miles an hour and i think on 89 you can have your parents drive that fast  just look out the window and you'll see everything whizzing by That's how fast you put your hand out the window to drive that oh legally for science for education we got a question from claire who says my whole family adores your show so please send along our thanks for such a fantastic program.
