- How can a half full bottle of water and half full glass of water move on their own accord?
Hi all. I'm a bit confused. I was lying in bed last night - on one side of a very big bed, not moving. When all of a sudden I heard a big crashing sound of things moving and falling. I switched the light on and on the bedside cabinet on the opposite side to me, a half full bottle of water and a pint glass half full of water had fallen off and were both on the floor. A little freaked out by this as I hadn't moved at all. I was well over a metre away, there was no gust of wind or any kind of vibration nearby. Can anyone explain this under the laws of physics? I'm beginning to doubt my sanity!
