Breaking a glass is no fun but don't add injury to insult by leaving miniscule glass shards behind just waiting for the next pair of bare feet to come along. Walk safely with this easy trick (using something you have at home right now).
Grab your masking tape!
Once you've vacuumed or swept up all of the visible glass pieces, use a wide strip of tape to pat down the scene of the accident. The leftover shards will stick to the tape instead of your feet.
I like to wrap the tape completely around my palm — sticky side out — to get the most control (and hand protection). Then, when all the glass is lifted, I carefully slide the tape off and throw it away.
This trick works best on hard surfaces like wood or tile or even on a rug if it has a low nap.
I'm always surprised by how much glass is still left behind after I think it's clean.
