Carolyn and Elliot demonstrate angular momentum by sitting on a rotating platform and moving a bicycle wheel around.

Elliot show how sound does not travel in a vacuum by ringing a ordinarily loud bell inside a jar where the air has been removed. He then puts marshmellow peeps inside and we watch them expand as the air is removed from the jar.

Carolyn make large bubbles and talks abbout shapes and colors.

Jim shows us a vacuum cannon where atmospheric pressure fires a ball across the gym.

Carolyn shows us how to stack a bunch of boards over the edge of a table. It looks like it will fall, but it won't as long as we keep the center-of-mass of the stack over the table.

Elliot throws a large disk across the room. It has a weight inside so that it wobbles.

Levi shows us what is called a "non-Newtonian Fluid". It hardens as it is poured or punched. He drops a bag of it containing a raw egg from the balcony and the egg does not break because the fluid hardens around the eggs as it lands.

Kyle shows us how a guitar and feed back work. Rock and Roll dude!

Mike Cullin drops various object through a tube. Some go slower than other and he explains how this work b because magnets can create currents in objects.

DJ shows us a supersized pendulum made with a bowling ball. He shows us how we can swing it back and forth and not get hit as long as we understand the principle of conservation of momentum.

Jose and Elliot shows us their latest Rube Goldberg machines that does all kinds of crazy things.

John and Carolyn talk about oscillations and wiggle a large spring back and forth.

DJ has too much fun showing us how air flow can be used to unroll a whole roll of toilet paper within seconds.

Joe shows us the power of energy stored in a trebuget as he flings a ball across the room.

Ryan swings a cup of water in a circle showing us how the water stays in the cup the whole time.
