My son has a Thomas & Friends Busy Book in the UK with tiny plastic trains inside. I thought that he had probably forgotten about them so I asked my mother to bring them over on a recent visit and I surprised him by freezing them in ice! The trains didn’t fit into a normal ice cube tray so I used Oxo Tot Blocks instead. They just about fit in!

When they had frozen I tipped them into a bowl and showed them to F.Trains In Ice - a winter science activity

I provided him with some warm water and an eye dropper. This method worked but progress was slow!Trains In Ice - a winter science activity

This also took longer than I had anticipated and I was really impressed that F stuck with the activity. He must have really wanted those trains. 🙂 Using a combination of more salt, more warm water and frequent water changes we got there in the end and finally freed all the toy trains!Trains In Ice - a winter science activity
