How can I create a bar graph for the science experiment "Blobs In A Bottle"

Question

How can I  create a bar graph for the  science experiment "Blobs In A Bottle"?

Answer 1

If your were to extende the demo into an experiemnt you can try to vary these things:
1. Does the temperature of the water affect the reaction?
2. Does the size of the bottle affect how many blobs are produced?
3. Does the effect still work if the cap is put on the bottle?
4. Does the size of the tablet pieces affect the number of blobs created?

 

Then for question 2 for example, you can plot the number of blobs for each different sized bottle as a separate bar in a bar graph.
