For Mac there is nothing better than science and all the slimey, moldy things and out of this world places that are a part of it. Now he's found out about Space camp and he'd really love to be able to go but his mother tells him he's going to have to earn the money himself. What can a fourth grader do to earn that kind of money? Mac gets himself a job walking a dog named Lemon Drop. But this isn't just any dog...this is a champion slobber machine. As Mac watches Lemon Drop's talent for drool, he and his friends decide to make a science project out of studying the delightfully gross yuck factors of dog spit. Sounds like fun to me! 208 pages Ages 7-10
