Credit to the original poster. I got this from another forum I visit and thought it might be enjoyed here, maybe even helpful. I'm usually pretty good at brain teasers and riddles, but didn't get this one. Hint - look for the simple.

You have 3 light switches in the basement. Each switch controls a separate, single incandescent fixture in the attic. Your mission, Mr. Phelps, if you choose to accept it, is to label the switches to match their corresponding fixtures. You can use no tools or equipment of any kind. You're allowed no help. You're allowed only one round trip from the basement to the attic and back to the basement. There are no windows in the basement or attic 3 floors above. It must be done on a sunny day at high noon.

This post will not self-destruct in 30 seconds. :scratchhead:

Didn't know there was such a thing. Am I missing something?

Turn two on, leave one off, go to attic and short out on of the lights that is on. Back downstairs you know wich light is which because the light you left off is off, the light you left on is on, and the the breaker has been tripped for the third.

I only figured this out due to the many times I've been shocked messing with live wires. :shocked:

Is there nudity involved in the adult version?

Unfortunately, I forgot to mention that all 3 fixtures are on the same circuit. After all, they're only 100 watt lamps and they're all in the attic. It's actually a given that they'd all be on the same circuit. Nice try, though.

What do you mean, "Is there nudity........" This is a family oriented community here. There are, however, ads for Geritol, Serutan, and retirement centers.

I can't believe the number of PM's I've received concerning this brain teaser. Hundreds, if not 1's. Out of all the answers I received privately, he was wrong too. So I've decided that rather than everybody wasting their time, wracking their brains trying to figure this one out, it's time to give the answer.

drdrdrdrdrdrdrdrdrdrdrdrdrdrdrdrdrdrdrdrdrdrdrdrdddrdr (drum roll)

Mark the switches A, B, and C. Turn A and B on. Wait 5 minutes. Turn B off. Go to the attic. The light that's on is A. The light that's off and cold is C. That light that's off and warm is B.

Please, please. No applause. After all, I didn't get it either.

Damn that was qucik :draw2wc:

You turn 2 switches "on" and leave 1 switch "off" and wait about a minute. Then enter the room, but just before you enter, turn one switch from "on" to "off". Once in the room, feel the lightbulb - if it is warm, but off, it has to be the last switch you turned off. If it is on, it has to be the switch left on. If it is cold and is off, it has to be the switch you left in the off position.

      Mounting Signs On EIFS

      By Rocco · Posted

      It depends on what's under the EIFS.   If it's plywood under the foam, then toggles are fine for a lightweight sign.  If masonry, we've come to like the titen HD (simpson strong tie brand) anchors or long wedge anchors.   The Titen HD screws are more user friendly than tapcons IMO.   They come in a variety of sizes, sometimes even at the big home centers.   Just check to see if it's densglass (fiberglass wall panels) under the foam.  Engineeners have told us that densglass isn't "structural" and that things need to be thru-bolted with uni-strut (or equal) sleepers across studs inside the wall.  A few years back, we were called out for an emergency call where someone had installed some large raceway channel letter signs to an EIFS wall that had densglass behind.  They used lag screws.  These held for a while but a heavy snow caused them to fail.   And toggles should work with Densglass but again not for any heavy loads.    In any case don't compress the foam too much.  A sleeve (mentioned above) would be needed for whatever the depth of the foam might be, though probably not needed for something light like an ACM panel.   if it's a really small sign, then appropriate exterior screws are usually OK going into plywood.

      Are there any recommendations for the best types of anchors to use for lightweight signs on EIFS?  <a href=" https://www.phoenixstuccocontractor.com/"> Phoenix Stucco Contractors</a>

      Pepsi logo vinyl colors

      By Rocco · Posted

      Hi   Can anyone tell me the right color red and blue translucent vinyl for the "new" Pepsi logo?  We have a local ice cream spot that recently changed from Coke to Pepsi and we have to replace the graphics on a couple of lit cabinets.   The customer sent me the logo in various formats but it didn't specify the correct colors.   I've searched but keep getting CYMK, etc. for the older logo - 2022 or so.   Thanks!
