It sure beats American festival food. Yummy! I thought of another experiment where you show the density of water buy coloring he water and mixing oil and water. They don't mix. One is heavier than the other. Can also show the density of sea water buy using an egg and salt water. An egg with sink in plain water, but as you continue to add salt it will float to the top. It is an easy and cheap experiment. I think there has been several blogs done on this one with using glass beakers for the drinks and so forth. Good luck!
Looks like fun!
Ha ha, I don't think I'll ever get used to drinking wine from plastic cups.
