“Bertrand, Air Whale” is an inflatable whale made from trash bags and sealed together with an iron. It is a project by Matt Jones.
Notes by Jones:
We breathed life into Bertrand, but sadly, he didn’t take flight. He tragically insisted upon beaching himself, and we ended up putting him out of his misery.
The idea was for him to be a solar hot air balloon, the air inside heating up and lifting him. I’m confident the main problem is too much mass of plastic in the pectoral fins, and tapered tail relative to how much volume of air those areas hold.
