A Science/Technical question...
At work.

While in uffish thought I stand there comes a pondrance.

Say I have an 'Infra red' night sighting system (Old style tech I know) what material might one use that would 'Reflect' or otherwise act as a kind of 'High ligh'.... much the way the road 'Cats eyes' and other 'Hi-vis' items do with visible light but in this case under the illumination of the IR?

Much cheers......

Are you using a 1st gen Russian night vision device??

Yes, the 'Fan fiction' is early 1950's type tech.

If you want a strong return, use a Corner Reflector

Look at reflectors on vehicles. They are made of an array of small corner reflectors, molded into the plastic. Try illuminating a red one with your scope and see what you get. If it doesn't work that well, just take two of them from a junk car and form some aluminum foil into that shape between them.

RE: A Science/Technical question...
I too have a science question. Not knowing how to start a thread on our forum if it is not good to attach it here maybe a moderator can move it for me. I shoot up insulin twice a day. At times when I pull the plunger back for the void to fill with insulin for a second or 2 there is what looks like air there but it fills up with the cloudy looking insulin rapidly. Question: Did I see nothing there for a second? Did a vacuum form in the body of the syringe? Or what? Does anyone with a more scienterrific edumacashion know what I am seeing?
Thanks

You're causing a partial vacuum. This is causing some of the liquid to rapidly change state from a liquid to a gas. This takes energy in the form of heat, so the gas becomes cool. The cool gas starts to condense, causing what is essentially a very short-lived cloud.
