Effectiveness

There are no test results to demonstrate that the system works.

Magnets may not be necessary because water pressure should close the opening. The mechanism proposed to raise the platform to release water may not work.

Durability

Diagram indicates sturdy materials

User-friendliness

Concept is user-friendly

Communication

It's hard to read handwriting.

EffectivenessThere are no test results to demonstrate that the system works.

Magnets may not be strong enough to hold the hatch shut. The water might empty before the magnet can hold the hatch shut.

Not clear how the foot pedal works.

Durability

Two legs would not be stable enough.

User-friendliness

Concept is good but the actual operation may prove challenging

Communication

It's hard to read handwriting.

Effectiveness

The whole idea is very good but the engineering of it may not work and there are no test results to demonstrate that the system works.

Using a small amount of water at a time is a good concept. I'm not sure how the cup will tip or how the funnel system works.

Durability

Durable materials have been selected.

User-friendliness

Simple user-friendly idea is good but the actual operation may prove challenging

Communication

Good scheduling of materials.

Too scary for kids. Kids may ignore the message because they haven't washed their hands and they are still alive.
