Magic Melting Ice Cubes
Simon Quinnell, from the National Science Learning Centre, shows how to carry out some ‘magic’ at the Christmas dinner table using ice cubes, a plastic chopping board and a frying pan. When asked to feel the plastic and the metal, people usually describe the plastic as warmer to the touch. They are then surprised…
Flying Tinsel
Simon Quinnell, from the National Science Learning Centre, demonstrates static electricity and charge using a balloon and a piece of plastic tinsel. Rubbing the balloon on a jumper builds up a negative charge on its surface. When the positively charged tinsel is dropped onto the surface of the balloon it is first attracted to…
Ice Melting Blocks Demonstration
In this National Science Learning Centre video, Simon Quinnell investigates the way different materials conduct heat using conductivity blocks and ice cubes. The video shows how the ice cubes melt at different rates depending on the thermal conductivity of the materials they are sitting on. Simon explains how this experiment can…
