Our regular party packages for travelling parties have one or two separate experiments that go for 30- 40 minutes total. This leaves us room for a short show and ending with a bang. We take the kids all the way through from the raw ingredients, measuring them out with test tubes, pipettes, spatulas and syringes and then mixing ingredients together to make their take-home creation. While it is one long experiment, it has a lot of different parts to each experiment.
