In one of my first year physics course they showed a great demo based on this principle. A student was challenged to inflate a huge bag as much as possible. They always did miserably, only filling the bag to about 1/8th. The lecturer then used this technique to fill the entire bag in one hit. A great demo that I'll never forget.
- pge 13y agoThis is a great demo - it's often done at kids' science museums as well, if they have an instructional area. Particularly with kids' tiny lungs, they can only fill a fraction of the bag, then when they do it this way, they fill a bag bigger than themselves. It's definitely memorable.
