Making Instructions (Login to see the full instructions)

Take your empty soy sauce bottle (brand doesn't matter, as long as the bottle has a diameter inside the neck of about 20mm) and soak it in warm soapy water. You should then be able to easily remove the labels. Use a scouring sponge to ensure the bottle is clean and free of glue residue.
If you have access to a sand-blasting booth, this is a relatively easy task to carry out, and you should be able to do this yourself. Remove the bottle's lid and ensure the bottle is completely dry. Place the bottle in the booth, lock the booth door and turn on the extraction. Place your arms in the booth gloves. Pick up the gun in one hand and place one foot on the pedal. Pressing on the pedal causes the gun to fire an abrasive powder. Use it to blast the surface of the bottle, while using the other hand to turn the bottle. To achieve an even frosted finish, work in over-lapping paths and ensure the whole surface has been completely blasted. Do not attempt to blast inside the bottle, as this will not be seen. TIP: Masking off sections before sandblasting preserves the surface finish of the sections covered. This can be used to create patterns and designs on the bottle. These will become very effective when lit.
The internal workings of this light form a colour-changing LED unit, and can be produced by soldering the following to a circuit board:LED(s)Lithium 'coin' cellOn/Off switchHowever, if you do not want to solder PCB, you can use an unwanted Christmas decorations.
Seen above is a glowing Christmas decoration purchased from Poundworld. This product was discarded after Christmas, but contains all the required electrical components.
Unscrew the base of the unit and, using sharp scissors or a scalpel, remove any unnecessary polypropylene casing. Reduce the size of the LED unit as much as possible until it can comfortably fit inside the soy sauce bottle lid.
The LED unit must fit inside the lid like so.
You may need to use scissors to separate the switch from the battery case in order to fit inside the bottle neck, and therefore allow the lid to be comfortably screwed back onto the bottle.
Once the LED unit is small enough to fit inside the bottle neck, you must attach it to the lid. Blu Tack proves effective in bonding the LED unit to the lid while allowing easy dismantling for battery replacement.
Once the unit has been mounted, the lid should look like this.
Use the switch to check the LED unit works.
Screw the lid back onto the bottle and your Soya, Light! is complete! simply unscrew the lid and flick the switch to turn on or off.
Soya, Light!
