Smart Fact: A Warning About Duct Tape

Duct tape may be good for almost everything, but for one particular usage—bandage substitution—people need to be cautious. Since Duct tape is manufactured in factories that do not comply to certain health and safety standards for their products, Duct tape can pose a threat of infection if applied directly to a wound. The same thing goes for super glue. This is why medical tape and glue exist for consumer use. It is ok though to bandage up a wound with Duct tape if a gauze pad is placed between the tape and the wound.

Stripped Screw-hole

Category: Multipurpose
Solution: When a screw-hole has become stripped, instead of re-drilling the hole, insert a small and thin object (a match stick for a wooden hole or a piece of solder for a metal hole) and screw back in the screw. This will carve threads into the inserted object.
Alternative product used and cost: Minimal
Result: Creates a tight seal without having to re-drill the hole.
Duration: Permanent if the screw will not need to be taken out again. If the screw needs to be removed later on, the inserted object may need to be replaced.
Original Options: Buy a tap or a drill and new screws and re-drill the hole.
Origin of AU (Alternative Usage): A classmate of mine has used this trick for many reasons, like attaching a wooden door to a hinge.
