Maintain two different temperatures for the two arms (eg, ice water and hot water) and watch it go!
This is a small, low power apparatus but one needs to exercise care with the hot water and follow all of the manufacturer’s recommendations.
Individual teachers are responsible for safety in their own classes. Even familiar demonstrations should be practised and safety-checked by individual teachers before they are used in a classroom.
