Do we still need to state the obvious? This DIY jar lantern is made from a CFL lightbulb and a jar that’s just big enough to contain the bulb. It’s easy to store, very handy. And because this lighting is enclosed in a jar, you can definitely use it even when it’s raining. :)

But what we like most about this DIY lantern is that, unlike standard emergency lights, you don’t need to charge it for hours before you can use it. (Not to mention that some emergency lights lose power if left unused for a long time, which will require you to recharge them. Good if you remember!) As long as you have ammunition for AA batteries, you’ll survive with this DIY jar lantern.

Its beautiful floating light effect makes it a nice side table or night lamp. You can also make it a travel essential to bring for camping trips or trekking.

Why not make one for each member of the family? :)

Open the disposable camera: Open up the disposable camera case. Be mindful not to touch the large capacitor which could potentially give you a nice jolt.

Cut away capacitor and flash: Discharge the capacitor by bridging the leads with a long screwdriver that you don’t care much for. Be careful not to be touching the metal part of the screwdriver while doing this. Once discharged, cut it from the board so that it will not recharge.

Also, cut the flash tube away from the circuit board.
