You Will Need
– A drinking straw- A fizzy drinks cup with lid- Sachet of sauce (we used ketchup but brown sauce, mayonnaise or anything else will work!)
Open the sachet of sauce and put the straw in it
Poke the straw through the lid and place the sachet inside the cup.
Now just pour in some fizzy drink and replace the lid
Leave the ‘drink’ in front of a thirsty victim and watch from a safe distance! Urgh.
