I am trying to do this expirament, and it will not work. Me and my friend and my biology teacher have tried it 3 times and nothing. We have done everything it says to do, and it won't work! After re-checking this website many times, and also looking over the internet mutiple times, we have done everything all of the different projects say. Do you have any suggestions?
