It’s actually not that uncommon, if you look it up, people have made even larger trees with more plastic bottles. This one is at a Chinese hotel. If lit right, it’ll work great. Lit wrong and you’re sitting on a goldmine of bottles that should be at a recycling plant. If left outside in the US, this bottle tree would be gone by morning.
There’s a video – it was removed since it autoplays. If you want to see the video of this tree, then click on the link.
