I'm building a parabolic mirror and I made the paraboloid out of cardboard, but I need something reflective. I was thinking aluminum foil, does anyone have any other materials in mind? (Preferably common items that I don't have to go out and buy)Also, I have another question. I designed my parabolic mirror so that if you take the rim of the mirror, the focus is in the center. That way I can use plastic wrap or another clear covering to cover the rim, so I can put the target on it. Will it get too hot inside the mirror (from the greenhouse effect)? I define too hot as hot enough to burn me or damage the cardboard.
I'm afraid old age and obsolesce have pretty much rendered your lights useless. Sorry those were great lights in their day.
Well try these things: 1. restart your computer 2. Log in to the adminastrator account (if know addminastrator account is shown hit control alt delete twice on the start menu) 3. If that still doesnt work contact a technician.
yea i got hit in the eye with a nerf dart ant that really hurt but i guess if you dont wanna keep your sight in both eyes go ahead
