Need help :( Glycerol and Bubbles (1 Viewer)

[Rage01]

Hi,
MY science assignment requires me to determine how varying amounts of glycerol/glycerine affect the size of bubbles.

I've looked everywhere but i can only find that glycerol makes the bubbles last longer after being blown. I conducted my own experiment showing that glycerol makes it smaller but i need to confirm it.

All help appreciated

Glycerin - Glycerin is the secret additive that gives a bubble its extra strength. Don't be too shocked by the price on a bottle of high quality Glycerin. Contact the pharmacist at your local grocery store for availability. (Note: Some bubble recipes substitute Karo® Syrup for Glycerin due to the expense and availability of Glycerin.)

thanks for the reply but i've been to these kind of sites and they only tell me how glycerol helps bubbles last longer.

I need to know how it affects size.

Thanks again
