Practical Problems (2)

"Here! The liquid fertilizer is all gone, so I brought an empty water container. Where should I throw this away?"

"As usual, clean it thoroughly and give it as a water container to houses that don't have—no, wait."

Huh?

IBC (Intermediate Bulk Container) tank.

Why didn't I think of that?

Is it light? If you remove the steel pallet from the bottom, it's plastic.

Is it sturdy? Of course, with a steel frame surrounding the exterior.

The shape? It's a 500-liter, appropriately large, square rectangular shape, so if we tie several together like blocks and place boards on top...?

A spacious barge would be completed immediately.

We immediately collected IBC tanks that were being used as water containers in each house and tied them with wire. After gathering dozens, hundreds of tied IBC tanks and placing them on the sea, they floated... despite bobbing up and down.

It was a success.
