Learners place their hands on different metals and use an ammeter to monitor the flow of electricity from one metal to another.

Learners create a small explosion by collecting hydrogen and oxygen gas together and squeezing them into a flame.

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

Visitors use heat to shrink samples of polystyrene. They compare samples from containers that were shaped in different ways during manufacturing.
