Isang Litrong Liwanag (A Liter of Light), MyShelter Foundation’s latest venture, is a sustainable lighting project which aims to bring the eco-friendly Solar Bottle Bulb to disprivileged communities nationwide. 



Materials: 
- PET soda bottle
- Galvanized Iron (GI) sheet
- Rubber sealant
- Bleach
- Filtered Water




Step 1Cut approximately 9 x 10 inches of GI sheet (corrugated or flat)

i

Step 2At the center of the GI sheet, draw 2 circles (outer: similar to the circumference of the soda bottle; inner: 1 cm smaller). Cut the inner, smaller circle

Step 3Cut the 1 cm difference radially, making strips and bend upwards, perpendicular to the GI sheet

Step 4Using sandpaper, scratch the surface around the upper third portion of the soda bottle where the GI sheet will be placed, to allow the rubber sealant to stick better

Step 5Insert the bottle into the GI sheet until the upper third. Apply rubber sealant on the strips above and around the area below. Then, wait for it to dry.

Step 6Fill the soda bottle with filtered water and ~10 mL (2 capfuls) of bleach. 

Cover it with its original cap.
