Science Expo, pt 2

More physics fun outdoors!  Race got to try driving a segway... a little nervous at first.

... but soon enough was cruising like a pro... or at least, as well as any kindergartner can.

We heard some explosions, so of course all the boys wanted to check it out. ... prepping a big barrel with water and the liquid nitrogren...

and BOOM! huge water gyser at least three stories high.  the boys were practically drooling, lol.

more liquid nitrogen fun, this time with raquetballs and flowers.

in goes the carnation...

... looks okay...

... but the frozen flower crumbled at the slightest touch.

The frozen raquetballs created quite the show...


... as the once bouncy and rubber balls now shatter when thrown on the ground.

Race had fun (and a lot of exercise) playing with the trebuchets.

... there it goes...

they made all the little kids run after the balls right after launching them.

... and to think, the kids thought that this was just having fun, not just bringing the balls back so the college students wouldn't have to get them, haha.
