SWEET. Syringe hydraulics are all kinds of fun and I recommend everyone try it out.
Anecdote: in my podunk high school the shop teacher basically got the dregs of funding so couldn't afford much and essentially tooled the shop out of pocket, and much of the building materials available to us were taken from supply store dumpsters.
His med-industry daughter told him of a delivery of mislabeled syringes, and thus was a box of umpteen tubes & plungers delivered unto us with yard upon yard of discarded aquarium tubing, and we were told to "build a Rube Goldbergian stacking robot".
The task was to stack as many plywood discs as possible, these being about the shape of a hockey puck in half the volume. My geeky little team won, with thirty-odd discs stacked.
That was also the year my little group built a trebuchet in the school's back property, and to give a size of scale, the fulcrum was a torched-off bit truck tractor axle. All the other groups had built trebuchets as well, but of the softball-flinging scale. On field day, we flung everybody else's trebuchets across the field.
I don't figure any of that would happen in today's public school zeitgeist.
