An Earring Duplicator that can replicate a missing earring by simply inserting the surviving earring needs inventing right now.

I also need a Domestic Item Locator that allows me to tag household items such as scissors, sellotape, car keys, potato peelers, remotes so I can find them using GPS.

In my proposed countdown format TV programme “Your Top 50 Household Items That Go Missing”, the veg peeler would be number one.
