Engage in an exciting activity with your child, create with your own hands a holder for a light bulb for 3, 5 V. You can easily make it from a matchbox. With the help of such a lamp holder, you can decorate an artificial aquarium made of homemade fish or a dollhouse with illumination.
Necessary
- - Matchbox
- - foil
- - two paper clips
- - large safety pin
- - a bulb for 3.5 V
- - wires
Instructions
Step 1
Line the bottom and one side of the matchbox with foil. Poke the paper clip legs through the foil wall. The foil should not protrude from the sides of the tray.
Step 2
At one end of the clip, poke a hole from the top. Place a loop of a safety pin over it and insert a second paper clip. Unfold the legs of the clip so that they touch the inside of the clip.
Step 3
Poke another hole in the clip in the middle of the safety pin. Slide the tray into place as shown in the illustration. Press the light bulb into the hole so that its base rests against the foil at the bottom of the tray.
Step 4
Prepare two long conductors. Wrap the end of one around the clip on the box sleeve and the end of the other around the clip on the side of the tray.
Step 5
Check how the cartridge works by attaching it to the battery poles. If the light does not come on, check the entire circuit step by step.
