Bubble Additives and Lasting Power
Medium
What if a single ingredient could keep a soap bubble floating for nearly three minutes?
Prepare five bubble solutions, each with a different additive: corn syrup, glycerin, sugar, lemon juice, and plain soap as a control. Blow a bubble from each solution, start a stopwatch, and record how long it lasts before it pops. Repeat five times per solution and keep the longest time.
Compare your results to find out which additive holds a bubble together the longest.
Hypothesis
The hypothesis is that soap bubbles made from solutions containing glycerin will last the longest.
Method & Materials
You will mix different solutions in plastic cups, blow bubbles with a bubble blowing toy, and time how long the bubbles last before bursting.
You will need empty plastic cups, liquid detergent, water, a bubble blowing toy, corn syrup, glycerin, sugar, lemon juice, a stopwatch, a measuring beaker, and a weighing scale.

See what’s includedResults
The results showed that the combined solution of water, liquid detergent, and glycerin produced bubbles that lasted the longest. This proves that the hypothesis was correct.
Why do this project?
This science project is interesting and unique because it allows you to make bubbles that last longer than usual.
Also Consider
Consider repeating the experiment using other additives like vinegar or salt. Also, try to compare the results by repeating the experiment at different room temperatures.
