ABSTRACT

In the first experiment, it was tested to see how water balloons pop when popped with a push pin. It was hypothesized that the water balloon would keep the shape of the water balloons shape for a brief second. First, fill the water balloons and measure them. Second, video tape the balloons popping. Third, watch the videos. The results were that the balloon does keep the shape of the water balloon before falling to the ground.

In the second experiment, it was tested to see if water balloons would gain or lose weight when soaked in water for a week. It was hypothesized that the water balloons would gain less than ½ of the original weight. First, a few balloons and a bucket were filled up with tap water. Second, put the balloons in the water and leave them there for a week. Third, take them out and measure the weight of the balloons. Fourth, see if the balloons gained any weight. The results were that the balloons gained less than ½ of the original weight.


EXPERIMENTAL IMPROVEMENTS & FUTURE EXPERIMENTS

A major discovery is that water balloons can keep the shape of the filled water balloons for a short amount of time after being popped. If the first experiment was done again, some things to improve on are to pop the balloon in the same area, to fill up the balloons with the same amount of water, have the same weather conditions and have better balloons. Some future experiments could be done are to see if different pins, different liquids affected the way the balloons popped. If the second experiment was to be done again, some things to improve on are to have all the balloons have the same amount of water in them before the balloons are put into the water, have more trails, and have the same temperature water in the balloons to begin with. Future experiments could be that different types of balloons, different liquids, and different major differences in temperature when the balloons are put into the water. If the third experiment was to be done again, some things to improve on are to test more weights of balloons, and to have more trials. Some experiments that could be done in the future are to see how different liquids in the balloon affect the distance that it flies and the temperature of the balloon.
