a is. For this experiment, you will be filling plastic sandwich bags
about 2/3 full of water. Then you will take a sharp wooden pencil and poke it
ALL the way through the bag (and water). Poke pencils through the baggies
over a sink or outside. Try to see how many you can get through. For a
variation, you can also try pens or mechanical pencils to see what works or if
one prevents leaks better than the others. If it's nice out, consider doing this
experiment outside!
