We’ve been having brilliant fun doing experiments with ice cubes and crystals.
Take 2 ice cubes (the same size) and place one on a crystal (the bigger the better) and one on a rock / loo-roll / cabbage or anything of your choice that has been in the same room as the crystal for 24 hours (so it’s the same temperature)
Then watch the difference in the speed they melt, it’s amazing, in our experiments the Crystal one melted about twice as quickly, but try it for yourself, and definitely share it with a sceptic!!
There’s no sound as much of the video has been speeded up, otherwise watching it would’ve been…well…like watching ice melt!
