🔬#MESExperiments 54: SpillNot Centripetal Tray

In #MESExperiments 54, I showcase the amazing SpillNot centripetal waiter's tray, whose circular motion can balance a cup of water without spilling it over, even while performing a full 360 degrees upside down! The SpillNot works on the principle that circular motion involves a centripetal force that brings the tray back towards the centre of the circular motion — this results in the cup of water experiencing a normal force far directly onto the tray, which far exceeds the downwards force due to gravity. The most astonishing part is that even a straw placed in the cup barely even experiences any slight nudge as it moves at rapid speeds. I also place my phone in the tray with both front selfie camera and rear camera views to further illustrate this amazing phenomenon!
