Yes, there is a story here. Our district professional development day in February was dedicated to science. Exploding things in the name of science sounds like fun - right? Wait a minute! This explosive professional development didn't happen in February. It happened at the March 8th, professional development for language arts and math. As Paul Harvey would say... here is the rest of the story...
1 cold unopened diet pepsi can + 1 LCD projector (turned on and projecting away) = explosion an hour and a half later
Our presenter placed her cold diet pepsi can on the cart next to the LCD projector. Heat caused the molecules to move more quickly and finally popped the top clean off the top of the can. A picture is worth a thousand words so here you go. Well... that was one way to get our attention.
The moral of the story... don't leave your soda can next to an LCD projector. They put out a LOT of heat!!!
BTW - no LCD projectors were harmed. Several educators jumped into action and saved the day.
