What happened when you blew into the straw?

Answer 1

Blowing into a straw typically creates air pressure that moves air through the straw. If the straw is submerged in a liquid, this action can create bubbles, which rise to the surface due to buoyancy. If the straw is in a drink, it might mix the liquid or create a slight disturbance. If the straw is placed in a solid substance, like a sand or powder, it may cause movement or displacement of that material. The specific outcome depends on the context and medium you are using the straw with.
