Is there a draft warning against floods? I am in eight classes. I want to prepare a model science project. guys please help me as soon as possible
A voucher is a simple device to notify you of your bathroom is going to overflow (and thus flooding the bathroom).
You have a simple circuit with a battery connected to a buzzer in series, which is connected to two arms of equal length (not connected) that hang in the bath at the desired level of filling.
When the water reaches this height, the water fills the circuit between two teeth and the alarm sounds, notifying you that water is the right height - so that you can now stop the tap.
