Door Jammer - allows you to open and close baby's door without making a sound. Keeps little ones from shutting themselves in the room. (This would be a great gift for new moms.)
Keep one in the shower filled with a mixture of half vinegar and half Dawn dishsoap. Use it to wipe down the shower while you are in there and your shower will always be clean. Must try this!
Glue a magnet to the bottom of the hammer so you don't have to hold nails in your mouth while hanging pictures. MIND BLOWN
