MYSTERY OBJECTS

[Big Kev]

Not a keyhole. Stanley is right that it's under a microscope but what is it?

[Gloria]

Cheese? Clutching at straws a bit here.

[Big Kev]

Not cheese. Think about a bag of chips.

[Gloria]

Salt crystal?

[Cathy]

Baked not fried...

[Big Kev]

Salt crystal?

That's the stuff, well done Gloria. It's part of a salt crystal under a scanning electron microscope.

[Gloria]

That was a good one

[Stanley]

Try this one.....

[Big Kev]

Snooker cue tip?

[Cathy]

A light fitting , or part of.

[Stanley]

Sorry Kev, no. Your very warm Cathy but not there yet.

[plaques]

Looks like a temperature / pressure relief plug of the kind that the core melts at excess temperatures. Pressure cooker or boiler unit.

[Stanley]

Sorry Ken but no. It's far older technology than that. Go back to what Cathy said, she is closer than anyone else.

[Big Kev]

Jet for a gas lamp?

[Cathy]

Is it a lamp holder bulb socket

[Stanley]

Sorry Cathy but no. However you have helped Kev to get there, it's a gas jet for a gas lamp. In this case one that was used in a caravan. You're far too young to remember that technology Cathy!
Next one?

[Cathy]

Thankyou kind Sir

[Tizer]

Any suggestions what this might be?...

[Big Kev]

It looks like spider's legs.

[Stanley]

Or a much enlarged section of an insect wing, possibly a moth.....

[Gloria]

Spider.

[Cathy]

A bee

[Tizer]

No, sorry, it's nothing to do with bees, spider's wings, or moths. Keep trying!

[Cathy]

Fungus under a microscope

[Tizer]

No, not fungus but I can see why you suggested it (and likewise for the other suggestions above).
You're all focusing on biology - let your minds wander a bit!
