Bought an endoscope, ideas on what to do with it?

[victorgrant]

Hello,

Today, I bought an Endoscope which I found on hotukdeals, it plugs into your Android phone via USB OTG (basically the charging plug at the bottom) and then you get a display on the screen. It comes with LED lights around the camera lens which is on a very thin and long bendy end.
The thing is is was too cheap to not order one, but I can't really think of a use for it! I suppose if I happen to need to inspect something which is awkward to get to it might come in useful one day.
Anyone got any suggestions?

Please help.

I didn't find the right solution from the Internet.
