Viscosity and Jelly

We recently tried exploring viscosity of fluids using water, oil, golden syrup and honey. The main problem we had was that for some of the liquids the marble dropped too fast for us to time. With this in mind we decided to try the same experiment with different strength jellies.

I made three different jelly mixtures in test tubes.

Solution A – Normal Jelly

Solution B – Normal Jelly diluted with half water

Solution C- Solution B diluted with half water again.

I would recommend amending those dilutions a little. We found that even after 5 minutes the marble hadn’t made it half way through Solution A and it dropped though B and C too fast.

Can you draw a table to display your results? and make predictions before starting?

If you try this at home and improve on our method, do let me know!

Have a Viscosity Race, using different liquids down a board

Try the same race but large scale in the garden!
