A friend of mine and I are working together on a little experiment, which required the use of Daphnia. We decided to work at his house, which was a mistake. He has a very unique little brother who while we were out getting supply's decided to drink down the entire beaker of daphnia as a dare from his equally unique little friend. When we got home and realized what he did we had him puke out the contents of his stomach in the nearest toilet. The boy is about 7 years old and around 75 pounds, do you think there will be any serious repercussions from this incident?
