Advice on making a portable sound system

[toast1]

I need to make a system which makes a sound when two pads are touched.

 
These pads would go on hands, so the system needs to be small, and battery run, connected to a small unit that would make a sound.
The pads would be taped on to the hands, so would not be big.

 

Not sure how to make this, can anyone give advice?

Thank you

 If you cant get an answer here, have a look at 'hackster.io' in your browser.

Lots of projects and you can input questions to the community.

I've included a couple of pics but not sure they are uploading.
