The science behind this experiment
How can you turn a full glass upside down and not spill the water?
Turn a glass of water upside down and the water always falls out. That’s because gravity pulls the water towards the earth. Is there a way to turn the glass upside down without the water spilling out?
Make sure you’re doing this where a spill won’t cause a problem – there is a reasonable chance that water will hit the ground during this experiment.
Keeping it fully submerged, turn the glass upside down.
Slowly lift the glass, but don’t lift the open end of the glass above the surface of the water.

Questions for students
- What happens when two bodies at different temperatures come into contact?
- In the transition from liquid to solid state, what happens to the volume of water?
- What is the physical principle thanks to which an alcohol thermometer works?
- Let us consider the following problem. At the bar of a railway station a traveller is sitting at a table with a boiling tea cup and a small cup of cold milk. Since his train is leaving in a few minutes, what is the best action he can do to cool down his tea with the milk in a given amount of time?

This experiment is part of the ATP Mobile Lab — a self-contained laboratory that turns an ordinary classroom into a working science lab, with over 200 experiments in physics, chemistry, biology, robotics and engineering. Gali, the AI tutor built into ATP Connect, guides students through each step and answers their questions at the bench.
