Practical Life Activity: How to Assemble a flashlight (for kids)
How do you assemble a flashlight for kids? It may seem quite complicated but you can get it done in a few simple steps. Take a look!
Flashlights are usually very useful. Kids find them interesting to make use of and it’s a nice thing to give to any young child you find. There are even various flashlight designs found all over the Internet and around the world. They are usually made into different sizes, shapes, and colors. There are models that you can twist, shake, crank, click and so on. Yes, you could easily pick one off the shelf of any store but nothing beats giving a custom-made flashlight to a kid.
Also, if none of this flashlight is your ideal choice or you don’t just want to waste money getting another one for your kid due to obvious reasons; kids break everything, you can make your flashlight. It’s quite easy to do and you would only need some basic house supplies; no expensive parts would have to be purchased. And your kid can play with it freely. So, how exactly do you get it done? Take a look!
Get your supplies. The first thing which you would have to do would be to gather everything which you would need for your little “science project”. You don’t want to be running around midway through the whole thing. It could affect your concentration and the overall result. So, the best way to get it right is from the beginning.
To start with, clear a part of the house where you can work freely. If you don’t mind, you can invite the kids and other members of the family to watch you as you go about manipulating with your bare hands. It could end up being a nice time for the whole family to get together and have some fun moments. So, will you need it?
- A used toilet paper roll or you could opt for lightweight cardboard which you’ll roll into a small tube.
- Two D batteries
- Electrical tape
- 2.2 volts light bulb. For optimal results, don’t just make use of any bulb. It’s possible to also make use of a bulb from a string of Christmas lights
- 5″ (12.5 cm) long piece of wire
Tape the wire to the negative end of the battery. Locate the negative end of one of the batteries. For most batteries, this should be the flat end at the bottom. Expose the inner copper can a bit and tape it to this end. Make sure it’s tightly done and isn’t going anywhere, else it could cause the light to flicker. It’s possible to make use of a tin foil in place of the write but the results will be more unreliable.
Cover one end of the toilet roll or folded cardboard. Make use of the tape to completely cover one end of the toilet roll or cardboard. By doing this, you’re preventing any light from escaping and ensuring that the flashlight can work at optimal capacity. Failure to do this would give you a poorly working flashlight or affect the brightness of the light it produces.
Insert the batteries into the toilet paper. First of all, insert the wired end of the battery into the toilet roll. Make sure that the wired end of the batter is facing the taped end of the toilet roll and the free end is facing upwards. If the wire isn’t coming out of the other end, you may need to shorten the tube. Then insert the next battery into the tube. Let this battery face the same direction as the first one; the negative side of the upper battery should rest on the positive side of the lower one. This connection allows the flow of electricity from one battery to another and will light up the device.
Tape the bulb to the top of the battery. Now attach the bulb to the positive end of the battery at the top. Ensure that there’s enough contact between both surfaces; the battery and bulb. Keep the attachment between both sturdy. Attach with tape but make sure the bottom half of the bulb is still visible.
Light up the bulb. To do this, connect the wire to the silver part of the bulb. It should light up immediately. If it doesn’t light up after a few tries, you can check through the tube to troubleshoot for any problems. When it works, you now have a functional flashlight with an on/off switch.
Well, this seems like a pretty straightforward method. If you’re having any problems with this method, you can try out something else.
For this method, you’ll need two D cell batteries, two 5″ pieces of number 22 insulated wire with 1″ stripped off at both ends, cardboard tube of about 4″, 3-volt flashlight bulb, two brass fasteners, 1″ x 3″ cardboard strip, paper clip, tape, and a bathroom-size paper cup.
Attach the wire to the different ends of the brass fasteners. Make sure that the brass tabs are punched through the same side of the cardboard tube; these tabs will be used as the on/off switch. Next, tape the two D cell batteries together. Make sure they are firmly attached and keep the batteries into the tube. Tape the wire to the negative side of the battery. Keep the connection firm to avoid any flickering. Cut a hole through the cardboard strip and keep the bulb in it. Secure the bulb to the cardboard with the use of tape. Attach a wire to the positive end of the battery and the bulb. At this point, the bulb should have started flickering or have come on. Also, cut a hole in the paper cup large enough for the bulb. Cover the toilet roll with the paper cup. Make use of a pop tab to connect the brass fasteners. When the pop tab touches both it should come on and when it’s disconnected, the flashlight should turn off. Now, you’re done!
