Bottle, cutter or scissors, soldering iron, flame (I use a spirit burner which I made with a jar and cotton cord)
Step 2: Cut the Bottle
Cut the bottle. you will use the bottom but don’t throw away the upper part. there are many ways to upcycle every shred.
Step 3: Forming
Heat the edge over flame and try to give a nice form. but before forming your bowl, experiment several times with leftovers until you have the control over the flame. Smaller flame is more controllable. after re-forming the edge, try to heat other parts to give a good form.
Step 4: Piercing
Pierce the bowl with the soldering iron. continue to pierce as long as your patience allows. I can do it 4 hours before I give up. this time, I decided to treat only the edge, but I could go all the way.
Step 5: Repeat
Repeat the steps until you upcycle all the bottles you have. use them at home, give them to your friends, teach someone to make, even sell them.
