Fantastic video! There are several improvements over other versions I have seen - I like that they are connected!
Did you make the heating tool yourself? Time will tell how long these plastics last in the sun, please do continue to report your progress!
@ecoinstant thanks for the words of encourage and glad you have been following up. I (@mr-greens) made the tool and i also look forward to giving more updates as to how long the plastics will last in the sun but in the main time from preliminary research, it seems it will last for a long time.
