I remember the day when I found these really cool ice balls on pinterest and thought I’d try and make them in my freezer for the girls to play with. I was a bit impatient so went to investigate a bit early and was so excited when I found they were frozen!
As it turned out they weren’t quite as frozen as I’d thought and a huge pile of water escaped from the one I was peeling the balloon over but to my exasperated surprise and utter excitement I found I’d made something so much better…Ice Caves.
To Make An Ice Cave You Will Need
Balloons, water, liquid food colouring (do not use paste) and a freezer although if the weathers cold enough you could try leaving them outside.
1. Take a balloon and add about 0.5-1 tsp of food colouring depending on how big a ball your making or how strong you want the colour.
2. Next fill the balloon with water and tie a knot in the end.
3. Put the balloon in the freezer and leave for 5-6 hours. Take the balloon out when it is solid enough on the outside to give a squeeze without breaking and there is still water swishing around inside. You may need to adjust the time depending on how big the filled balloon is, so keep checking.
4. Over a sink carefully pull the balloon away. Depending on how thick the ice is you should get a natural break hole in the ice as the weight of the water causes the ice to break. This hole or two provides just enough space to add little toys.
5. Because the food colouring wasn’t stirred in and is denser than water it will sink to the bottom of the balloon forming a beautiful coloured base to the cave.
They made fantastic homes for the girls Playmobil and plastic animals. Which was constantly changing as the ice melted.
If you’re really lucky you might even get to find some ice crystals inside like we did with the clear Cave. Their jagged shapes jutting up from within the Ice cave like big icy knives.
