Another nice simulation that is prety close to actually doing it.
Quite realistic simulation with all the readings needing to be done with the uncertainty that entails. Hard to show with images, but the thermometer reading goes up, as does the plunger.
You actually get to drop the weights and have to read from the mm scale. It gives you a zoomed in view.
