1) The effect paint has on our environment. Asked Mr. Hendrickson and he said that paint was indeed toxic to environment, since all paints are either oil based or plastic based (acrylic). So unsafe treatment of the paint might cause environmental harm. Could test this hypothesis by watering plants with different concentrations of different paints.
2) Is laugher contagious? Just looked online and it actually is. Scientists have already mapped the brain and what laughter does to it. So it's a no go for experiment. But perhaps I can turn it into a study, since laughter is also beneficially related to health.
