This is the genius trick my 98 year old grandpa taught me. One don't panic if your phone screen is cracked. Apply an even layer of toothpaste over the screen, then cover the entire screen with tape. Rub it back and forth a few times, let the toothpaste fill in the cracks, then wipe all the toothpaste off and your screen is good as new. 2. Don't replace a broken bike handle grip. Hammer a piece of wood into the opening, saw off the excess wood, then find a bottle cap that fits and secure it to the end and the handle grip is firmly repaired. 3. If you accidentally lock your keys in the car, don't try to pry the door open. Stick a magnet to the end of the battery, then take a charging cable, connect one end to the keyhole, and attach the other end to the magnet. Slowly move the battery toward the door handle. Use capacitive sensing to trigger the unlock and the car door opens right up. 4. Don't throw away cracked plastic parts. Bend a spring into a wave shape, heat it evenly with a heat gun for a moment, then press the hot spring into the crack. Use it as a reinforcement frame. Next, heat a blade until it's red hot. Run it evenly over the surface so the plastic can spring fused together and the plastic part is completely repaired. 5. Hide your spare key inside a pipe when you need It just use a magnet against the pipe to move it along and pull the key right out. A thief would never think of it. 6. If if a screw hole is stripped and won't tighten, wrap copper wire tightly around the screw threads, then heat it with a flame for a moment, quickly press it into the stripped screw hole, let it cool and set, then remove the screw. The hole will have new threads so the screw locks in tightly without coming loose. 7. If the handle tab on your kettle breaks off, take the aluminum tube from a pop rivet and place it where the tab was. Split the end of the aluminum tube, line up the holes and hammer it firmly into place and your kettle is easily repaired. Eight. Objects mounted to hollow brick walls always seem to come loose. Heat a glue stick until it softens, push it into the hole to fill the gaps. Then the screw can grip tightly. Even heavy items can be mounted without coming loose. 9. Don't panic if a chair leg breaks, drill matching holes on both sides of the break, then thread a piece of wire through the holes in a crisscross pattern. This creates a tightly stitched connection and locks the broken chair leg firmly back together. 10. Low water pressure from your faucet. Cut the water pipe and add a T joint. Reconnect the main pipe to the faucet, then grab an empty plastic bottle. Wrap the bottle opening with a few turns of plumbers tape. Screw it onto the side outlet of the T joint. When the water flows in, it compresses the air inside the bottle. Opening the faucet then gives you extra water pressure. 11. It if your door won't lock from the inside, measure the width of the end of the door handle. Cut a matching notch into a piece of wood, fit it over the door handle. Now the handle can't be pushed down from the outside. 12. Use PVC pipe to reinforce a hanging light. A shaky ceiling light can be dangerous. Heat the end of the PVC pipe and press it into shape. Then drill mounting holes and secure it to the ceiling beam. Run the wires through the PVC pipe, fit the light socket into the reducer fitting, then put everything together and the light stays firmly in place without wobbling.
