Science never sucks, or does it . . ? Students will discover the truth about air pressure and “suction” forces using this clever drink holder. Slide the simple rubber ring over a soft drink can and it will make the can stick to any smooth surface!

Lifting it will require a force of 983N (at sea level) or a clever flick of the finger to cheat scientifically. Holds cans, bottles, glasses or any object up to 7.5 cm diameter.
