Simply offer your work colleague a can of pop on your break. Offer to buy it them as well - they’ll probably think you’re great! Then, using a pin put a hole in the can at the bottom and drain the contents.

You’ll have to be careful here – it’s not advised to have an accident and need first aid over this!

Once you’ve dried the can off, leave it somewhere on their desk for them to look forward to later on. Then sit back and get ready to laugh at their disappointment! You’ll have to deal with it if it doesn’t go down well though!
