Race your mate and shake your coconut down through the palm tree! The first one to reach the bottom is the winner. To make this, you'll need quite a few yoghurt pots! The trunk of each tree is made from yoghurt pots - nine make a good size tree but you can build it as high as you like. Pierce a hole in the bottom of each yoghurt pot with a sharp pencil. This will allow the coconut to travel to the bottom of the palm tree. Use a pair of scissors to make the hole a bit bigger. Put the holes in different positions on each yoghurt pot, so that when you drop the coconut in the top it won't just fall all the way to the bottom. The coconut is a little wooden bead. Test the holes to see if the coconut will drop through. Once there's a hole in each yoghurt pot, build up the trunk by evenly spacing the pots and sticking them together. Keep one last yoghurt pot - but don't attach it to the top of the trunk as you first need to put the palm tree leaves on it. Cut out a leaf shape from crepe paper. Fold it in half, and use some scissors to fringe the edges. Cut a pipe cleaner - green is best - a little bit longer than the leaf. Paint the back of the pipe cleaner with a bit of glue. Then stick the leaf to the pipe cleaner. Leave a bit of pipe cleaner at one end. When it's dry, bend the leaf into shape, like this. To fix the leaves to the yoghurt pot, make some small holes around the top. Push the pipe cleaner through one of the holes, bend it up on the inside and secure it in place with some tape. Position the leaves around the top of the yoghurt pot. Stick the pot on the top of the trunk like you did with the others. You can leave the trunk unpainted - this has its advantages as you can see the coconut as you shake it through the maze of holes. If you paint it, paint each pot before you stick the trunk together and mix a bit of PVA glues to the paint so it will stick to the pots. Ready, steady, shake!
