Iron Science Teacher

Battle Fruitcake

Welcome to the Phyllis Wattis Webcast studio!

Linda Shore holds up this week's challenge, fruitcake!

Iron Science Teacher Contestants

The contestants have 10 minutes to create a science lesson.
Karen, Don, Eric and Paul

Each contestant presents a science lesson for 5 minutes.

Paul asks the audience which will hit the floor first when dropped together
a small piece of fruitcake or a large piece.

Don Rathjen measures the density of fruitcake, and finds that it just barely floats in water.
He then compresses the fruitcake by sitting on it, the result is denser fruitcake
which sinks in water.

Karen blends the fruitcake in a blender with and without metamucil.
She then squeezes it through a sausage casing.
"This is your colon on fruitcake!"

Eric drops a piece of fruitcake into a combustion chamber full of molten potassium chlorate.
He produces a rocket motor powered by fruitcake.

Lori Lambertson has the last word

She suggests that the best experiment would be to simply eat the fruitcake.
"After all has anyone ever done that?"

When the presentations are done the audience votes.

The winner receives, of course, a fruitcake!
