I’m sure everyone has seen the beautiful coloured ice balls that have been doing the rounds on twitter and Facebook. If you haven’t then take a peek here.
Well, you can use the same principle to make the most fabulous ‘Ice Caves’ for children (and adults) to play with.
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.
