Steps

1. If your family eats O-shaped cereal, thread them all onto a piece of string and put them back in the box.
2. Make a fake 'fried egg'. Arrange a spoonful of natural yogurt in an oval on a plate. Pop an apricot half in the middle. Serve it up to your family with a rasher of real bacon.
3. Put an empty eggshell upside down in an eggcup and surprise someone with a boiled egg that's got nothing inside.
4. Scoop a small hole in an apple with the end of a spoon and insert a sweet gummy worm - yuck! Create Simple Mashed Potato in an ice cream cone - tell your guests it's vanilla-flavoured ice cream.
5. Swap the sugar and salt over.
6. Scrape the butter icing from the middle of a biscuit and replace it with toothpaste. If toothpaste doesn't sound like a good idea to you, use ketchup or mustard instead.

1. If your milk comes in cartons, turn it blue with a few drops of food colouring. No one will notice until they pour it out.
2. Replace apple juice with warm flat beer, or do it the other way around.
3. Add food coloring to water to make it look like a glass of juice or punch. Make Jello Shots following the instructions on the packet. Before it sets, pour the jelly into glasses. Pop a straw into each one and put in the fridge. Wait until your jelly sets before you serve up your 'fruit juice'. Watch your guests try to drink it! With a pin, pierce several holes in a drinking straw, then pop it in a glass of juice.

Warnings

• When using the pin, be careful not to pierce your finger.
• Ingesting too much fluoride toothpaste can cause unpleasant gastric effects. Make sure the tooth paste you use doesn't contain fluoride.
• Flat beer is probably a bad idea for people under 21 (according to the United States Government).
