Exclamation Simple Earthquake Detector

Can anyone give me an idea to build a model which flies (miniature rocket assisted take-off systems attached to an aeroplane model) or at least any model (like burglar alarm, electric circuits of different very simple electronic gadgets etc.) ]
OR
any model related to physics

Hi.

Are you intrested in an earthquake alarm?
Is very easy to build but it will take a lot of words to explain it how.
If you are intrested, reply yes and I'll send you and image of how to build it.

Default earthquake alarm

Does it comprise a very elaborate design/setup? I would love to know how to build one!

Dear Mad Scientist

Hi.

No, it does not comprise a very elaborate design/setup?

For this model you will need some home materials as aluminum paper, a plastic can, batteries and some construction materials such as wood, nails, electric wires and an alarm.

For the setup you will need mounting tape and a good spot in your house where you can assure there will be no air flow that can turn on the alarm.

It is very easy. I can upload an image and a more detailed description if you would like to.

Best regards

Oscar
