Metal object in spark plug hole

Use a mechanic's pick to make sure the small piece is loose and not jammed in place. Then use long pointed tweezers to grab and remove it.

Thanks for the advice guys. I did try with a pick and tweezers but it proved too tricky due to the fact I couldn't see in the hole and have tools in there simultaneously (due to the fact the hole is at a right angle to where I can get my eyeline, I could only see in the hole with my phone camera).

In the end I went a bought a set of magnetic screwdrivers (which I didn't own, this is my first attempt at servicing a vehicle, I'm new to this), and managed to get it out. Panic is now over.

Thanks again :)

Bfore I treated myself to some magnetic screwdrivers, I used an ordinary screwdriver blade- or flat piece of steel, which attached itself to the magnet off an old speaker. The magnetic quality magically spread down to the other end of the blade, and on condition the errant piece is also steel, it gets picked up. Obviously it won't work if the magnet is on the handle...
