Science Expo, pt 3

Moving on to the Chemistry Department! (... do we look tired yet?)

They had lots of little mini-experiments all shoved into one laboratory, but they were really kid friendly too.  This one showed water cyclones in soda bottles.

Here, Race learned about water tension using canning jars.

This experiment taught about the difference in water pressure.  Each soda bottle had little vials inside with varying amount of pressure so that when the bottle was squeezed, the vials sunk, and when let go, they floated.  Plus, this one gets points for creativity - they decorated the vials to look like a little diver and a ballerina.

We're making a connection! ha.ha. ha. -_- This particular one was about making or breaking electrical currents, so when we weren't touching, the current to the ball was broken and the light wouldn't turn off.

... I think this was about wind tunnels? maybe??

... another kinda lame one, making sticky bubbles out of ... something... kinda slow and they didn't really say much.

Learning about density using diet and regular cokes, and then wrapping them in foil to decrease the density.

... can't recall the "lesson" to be learned, but basically it was poking long skewers into balloons without them popping.

Afterwards, relaxing and letting Danny spend some "quality" time with the nephews...

... or more accurately, becoming a human jungle gym, lol.
