My Science Experiment

In about 2 weeks, our school is having a science fair. I am doing my experiment on crickets. I'm trying to see how different substances repel crickets. I made a contraption with two bottles, and a toilet paper roll. I put 10 crickets in one bottle, and put some tomato slices in the other. Connecting the two bottles was the toilet paper roll.  I put each substance (cinnamon, baby powder, and salt) in the toilet paper roll, and waited to see how many crickets could make it to the other side. The crickets hated the cinnamon, loved playing in the baby powder, and actually ate the salt. It was really cool to see them eating the tomatoes.
