Ice lanterns

A lovely idea from the Woodland Trust:

You will need:
Two small, empty plastic tubs (they need to be different sizes so one fits in the other)
Some cold water
A few pebbles or stones
A very cold night (or a freezer)
A candle or a tea light

How to make:

1. Half-fill the larger tub with water.

2. Put some pebbles into the smaller tub, then place it inside the larger one. (The smaller tub should float without touching the bottom of the bigger one, so you might need to experiment with the number of pebbles you use to weigh it down).

3. If it's a really cold night below zero degrees centigrade (the temperature water freezes), place the tubs outside to freeze the water overnight. If it's not quite cold enough you can put them in the freezer for a few hours instead.

4. When the water has frozen, carefully remove the ice from the tubs - it should look a bit like a candle holder.

5. Put a candle in your ice lantern and use it to turn your garden into a winter wonderland in the dark, gloomy evening.

6. More ideas - experiment with different sized containers; use glitter or food colouring in the water to make your ice lantern stand out; collect natural materials to freeze in the water and decorate your lantern.
