Heat from your hand increases the vapor pressure of the liquid in the lower bulb, forcing it into the upper bulb. An impressive display of vapor pressure and the force gases exert.

Rated 5 out of 5 by from Fun way to explore vapor pressure My students love these. I ended up buying a whole class set because they don't want to share. I love when science looks like magic. They are fragile but with specific handling instructions we haven't broken any yet.

Rated 5 out of 5 by from Great for showing how molecules change when heat is added I have used this to describe concepts of how matter changes when heat is applied. Students LOVE it.

Rated 5 out of 5 by from WAY FUN! This little object has become a center of attention in our living room. The kids love to see how it changes during all different situations. They even run inside the house on cold days to watch how it has an opposite effect on cold hands. Very engaging for all ages in our house from 5 to adult! The best part is the kids come back to it time and time again.
