About This Product
Each bulb is filled with a different liquid and the trough is filled with hot water, so all of them warm together. As the columns climb their tubes at different rates, the class can compare thermal expansion directly, without having to reconcile separate experiments. The bulbs can be easily removed and refitted, and the funnel formation on top of each makes filling easy. The Expansion of Liquid Apparatus can be exported to Vanuatu, Fiji, Kenya, Bangladesh, Libya and Timor-Leste.
