ELI5: Sometimes when my tongue rolls in a certain position water sprays out from under it. Is this normal? And why does it happen?

This is called gleeking, and is completely normal. Your salivary glands are located underneath your tongue. When you move your tongue in certain ways, you express (put pressure on) these glands, which will force them to release any saliva that the glands currently contain.
