My 8th grade son is testing the effect, if any, of the energy drinks Monster, Amp, and Red Bull has on performance. He is using 4 mice, one for each drink plus one with water for control. He built a maze for them to run through and is training the mice to know that there is a treat at the end. He will give them the drinks only an hour before testing, the rest of the time they are drinking water. Then, he will time them and compare times. But we are concerned that the drinks may be too strong for them? Should they be dilluted? If so by how much? We also don't want to lose the potency of the drinks. Thankyou.
