in science today we were learning about lava lamps and how to make them we put a pil in the oil and the air/carbon dioxide will float up to the top then all the way down I found it hard to chose a color with my group. we didn't really like how yellow looked though. I found it easy to slightly dunk the cotton bud into the colored milk. I really enjoyed making the lava lamps and adding food coloring Next time I will get a better color so that it makes the oil look more cool.
