The secret behind formation of bubble is the surface tension between the molecules. Water is a polar molecule, so it has plus and minus ends just like magnets that attract each other. When the water molecules align with each other, they stick together creating surface tension. You might think that it is the surface tension of the water that holds the bubble together. Actually the surface tension of water is too strong to make a bubble. This is why when we try to blow a bubble with plain old water, it won't work! A good bubble solution has detergent added to it to relax the surface tension of the water, allowing it to have more elastic, stretchy properties. Now it can act more like the skin of a bubble, stretching out nice and thin, trapping air inside of the bubble like a balloon.
Hypothesis:
By adding glycerin or corn syrup will make the bubble solution better
Materials/Procedure
Tap water, Corn syrup, Glycerin, Detergent, 3 Jars, Pipe cleaners, measuring cups & spoons, stopwatch
Procedure:
1. First we made the bubble solutions and labeled them in jars.
2. Then we blew the bubbles with pipe cleaners and time how long the bubbles lasted.
3. Finally we wrote down wich bubble solution lasted the longest and found out the average amount of time the bubbles lasted.
