This is however, no ordinary bowl. It needs to:
- Have a hole in the bottom that we can insert a small propellor into, that would then be attached to a motor.
- Be circular, however one 'side' needs to be flat, as it will be placed flush against a wall. So it needs to be as if we cut off a section of the bowl.
- Be watertight once we attach the propellor/motor.
As background, this is part of a digital/physical installation a group of students and I are making for an assignment. Basically we are planning to find a big bowl and then cut it, however worst case scenario is that we can't find one so I'm asking for advice/ideas on how we'd go about building one in that case.
So yeah, any reccomendations on materials, etc would be awesome
Oh, also needs to be relatively large, maybe looking for 1-2m diameter and 30-50cm deep.
EDIT: Here's a basic pic of what we are looking for.
