Handicrafts-4. Self made flashlight The specific production method is as follows: lift off the cover of one end of a waste can (such as Lulu beverage can) and knock the other end concave with a round hammer. Roll up two No. 1 batteries with thick corrugated board, and put them into the tank with the positive pole facing up and the negative pole facing down. Find a suitable plastic cover (for example, the box cover of the magic big roll can be buckled on the Lulu beverage can), and dig a small circular hole in the center of the box cover. The size of the hole is appropriate to plug the bulb tightly. Insert the bulb base into the small hole. Take a section of wire search, peel off the wire skin at both ends, wrap one end around the lamp holder, and pierce a small hole from the side of the plastic cover at the other end. Put the plastic cover on the can. Check whether the bulb and battery are in close contact. Here's a disposable flashlight. When in use, use your thumb to press the wire passing through the side wall on the unpainted weld of the can, the flashlight will shine, the thumb will jump away from the wire, and the flashlight will go out, which is very convenient to use.
