=ABSTRACT= ====The purpose of this experiment was to test which brand of bubble gum blows for the longest. It was hypothesized that Hubba Bubba would blow for the longest. This was hypothesized because it was the thinnest brand of gum. It was also hypothesized because it was the softest brand of gum after it was chewed. The first step of doing this experiment was setting the timer for 30 seconds and pressing go once the gum was put into the mouth of the person who was testing this experiment. Next the person blew into the gum. The person blew the gum until the gum popped. When the gum popped the timer was stopped. This was done three times for each brand of gum and was recorded in a table. In the end Bubble Yum bubble gum ended up blowing for the longest. An Inference for why Bubble Yum ended up blowing for the longest is because it was the thickest and roughest after chewed out of all the gums. The purpose of a second experiment that was done was to test if the amount of seconds gum is chewed affects how far it can be spit. In the end it did as expected and chewing the gum for 60 seconds or 1 minute spat the farthest.==== =Experimental Improvements and Future Experiments= The experiment could be improved by using a bike pump to blow the air into the bubble instead of using human breath to blow into the bubble. A bike pump would be used because it never loses air, but humans run out of air and have to inhale again. A future experiment that could be performed was testing the strength of gum after chewed. For the second experiment it could be improved by keeping the mouth closed when chewing for the amount of required seconds. This would improve the experiment because it would let no air into the gum so it might not change the results of this experiment. A future experiment that could be performed was testing if gender affects how far you can spit gum.
