I think there was a science experiments book for kids that dared me to drink water from a glass upside down through a straw while hanging from monkey bars or something. It was meant to show how our body deliberately moves food towards the stomach instead of solely relying on gravity, but instead it showed that I my legs were too weak.
A shame these experiments are deemed to dangerous nowadays and people have to show their ignorance online, simply because the new metal straws have pierced the brains of anyone who did them.



I implied that I fell from the monkey bars, and since I was drinking through a straw, I fell head first onto my water glass with the straw in my mouth that was below me. A common misconception of metal straws is that they are dangerous and can pierce through the mouth into the brain.
I guess I could specify where the glass is in the experiment.
