This game of Pizza Roulette is a brilliant centrepiece for a Sleepover Party. Who knows what dares you and your mates will have to do? Here's how it works - you and your mates take it in turns to spin the pizza. You must take the slice that stops in front of you! But first - no Sleepover Party is complete without coloured popcorn and marshmallows. Mmm! And how about making the Finger Tips Splodge Cakes? Yum! Or make chocolate brownies decorated with your friends' names. For when it gets dark, paint yourself a glow in the dark sign. And use glow in the dark oven bake clay to make hanging stars. You could use some glitter paints to decorate push lights, like these. Once you've got plenty of food and decorations sorted for the Sleepover Party, you can make the Pizza Roulette game. Start with two polystyrene pizza bases. Draw around one of the pizza bases onto a piece of corrugated card. Then cut it out. Use a ruler to divide the circle into eight pieces, and then cut them out too. On one of the polystyrene pizza bases, draw lots of little bits to use for the pizza topping. This one's got circles for pepperoni, strips for bits of peppers and hoops for slices of olives. Then cut them out. To make the rest of the topping, cut up all the left over bits of polystyrene base into tiny pieces. Put the pieces into a bowl and add a generous amount of PVA glue. Give it a good stir! Then add some flour to thicken up the mixture. Next put a generous amount of the mixture onto each cardboard slice. It's a good idea to put the slices on some plastic so that the table or surface you're working on doesn't get covered with glue. Add the bits of pepperoni, peppers and olives. Once the whole thing has dried, paint it. Use different colours for the different toppings. To make the tray, stick a rim of card around the other polystyrene pizza base. This will stop the slices flying off when you spin the pizza game. Next, cut the end off a sweet tube, then snip all the way up the tube. Squeeze the sweet tube together and stick it back in place with tape. The tube should now be narrower than it was before. Then use scissors to cut strips at one end of the tube. Fan these out and tape them to the bottom of the tray. . For the base you'll need a yoghurt pot, a piece of card that's bigger than the yoghurt pot, some modelling clay and a pencil. Place the modelling clay on the card and the yoghurt pot over the top. Push a pencil into the bottom of the yoghurt pot, through the modelling clay and into the card. Secure it in place with some tape. Paint the base and put the pizza on top. Use a very small amount of tack to attach a dare to the bottom of each pizza slice. Once you've chosen the dare, remove it from bottom of the slice. You might be lucky and get a piece with no dare... or on the other hand, you might be singing with a pair of pants on your head. Good Luck!
