STEM WALL - Heat Sensitive Fun Board

The Heat Sensitive Fun Board has a dark special plastic film fitted to its surface. When children place their warm hands on it and then remove them, they will discover that a colourful handprint has appeared. The hotter their hands the clearer the handprint. Different colours appear depending upon the heat being transferred. For a quicker response, children can heat their hands on a water bottle filled with warm water. This will transmit the heat more efficiently to the surface and the colour changes will be more rapid and vivid as a result.
