Everyone loves a good experiment! A recent library book called The Ben Franklin Book of Easy and Incredible Experiments allowed for Daniel to mess around (literally) and learn about pressure. For an easy and inexpensive demonstration of pressure, gather a clear plastic cup, a large index card, and a sink! Fill the cup to the brim with water. Place the index card squarely over the cup. Flip all of it over carefully (over the sink!). If done right, the pressure will hold the index card to the cup for a few moments. Pretty cool, huh?
