Tell-Tale Sister!

I have this really annoying twin, shes always telling off me, the bad thing is most of the time my parents punish me for it! Even the silliest thing, like throwing a sock at her, gets me banned from the ipad for 2days, when I refuse it's gone up to a week! I've had a good search through your pranks and overall I like the bucket of water on the door, myself I'd like to play a similar prank, but one that has minimum evidence, as for the bucket, a wet carpet. Please could you find some?

Damien: It's rather difficult to prank someone in your home without leaving a trail. I'm assuming you don't have another sibling to frame for your mischief. You might want to try one of the shower pranks, since the evidence washes off very quickly. Cold water leaves no evidence in a shower :-). Another idea is to salt your twin's toothbrush or toothpaste.
