Skittles
This is a really easy one. Firstly you will need half a dozen empty bottles - shouldn't be too hard. Then you will need Christmas wrapping paper. Roll the packaging into a ball and tape it. I did a small ball first then covered it again to make it bigger. Set up a piece of wood between two buckets then balance the bottles on the timber. Now all you have to do is knock the bottles off. You can handicap the dead-eye dicks in the family by making them throw from further back than the more moderate throwers.
Pinata
This is the one where you hang a bag full of sweet surprises from a tree, blindfold a volunteer, give them a big stick, disorientate them by spinning them around then encourage them to smack the bag as hard as possible in the hope of popping the bag. Use Christmas wrapping and any spare sweets, chocolates or treats. The trick here is to make the bag hard enough so that it doesn't pop first time or alternately take so long to destroy that everybody loses interest. I've made a layered pinata so the candy comes out little and often. The shape is usually an animal like a donkey but with all this seasonal paper you might knock up a reindeer or a topical figure in popular culture. We have just had an election after all.
Sleigh
This is an easy one but you will need a steep hill with long grass. Simply collapse a box to form a flat base and slide down a steep hill on top of it. Dry long grass will give you the best slide action. I also recommend stuffing some newspaper down the back of your pants so as to give you some padding.
Cricket
As with skittles, make up a paper ball, use a cardboard box as wickets and any stick will do as a bat. A bigger ball will make it easier to hit and enable everyone in the family to be involved. Non-stop cricket is a good fast option and bat-down gives everyone a chance to shine.
Puppet show
I really like this one, especially if it's a bit wet outside. You can relive, embellish and share family stories, (Uncle Mike burning down the neighbour's shed after borrowing their mower), re-enact a scene from a favourite movie (bank robbery, Heat) or tell an important historical event (the birth of Christ, the re-birth of Winston in Parliament).
Merry Christmas to you and yours.
