Cut out the square and the circle on the sheet metal.  Test placing the bottle through the circular hole.  The bottle should fit snugly, allowing 2/3 of the bottle to hang down through the bottom of the sheet metal.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/b\/b5\/Make-a-Solar-Bottle-Bulb-Step-9Bullet1.jpg\/v4-459px-Make-a-Solar-Bottle-Bulb-Step-9Bullet1.jpg","bigUrl":"\/images\/thumb\/b\/b5\/Make-a-Solar-Bottle-Bulb-Step-9Bullet1.jpg\/aid2687963-v4-728px-Make-a-Solar-Bottle-Bulb-Step-9Bullet1.jpg","smallWidth":460,"smallHeight":306,"bigWidth":"728","bigHeight":"485","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"} Don't overfill as you will need to add bleach. Allow the bleach to permeate through the distilled water without shaking the bottle.  Make sure you add a liberal amount of sealant in order to avoid having rain or other outside elements escape through the hole. If possible, add sealant or, if it is not available, M-Seal to the sheet metal to adhere it to the roof.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/b\/ba\/Make-a-Solar-Bottle-Bulb-Step-14Bullet1.jpg\/v4-460px-Make-a-Solar-Bottle-Bulb-Step-14Bullet1.jpg","bigUrl":"\/images\/thumb\/b\/ba\/Make-a-Solar-Bottle-Bulb-Step-14Bullet1.jpg\/aid2687963-v4-728px-Make-a-Solar-Bottle-Bulb-Step-14Bullet1.jpg","smallWidth":460,"smallHeight":314,"bigWidth":"728","bigHeight":"497","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}
Summary: Measure the circumference of the top 2/3 of the bottle and transfer the measurements to your structure's roof. Transfer the same measurements to the extra piece of sheet metal. Fill the bottle almost to the top with distilled water. Top off the bottle with bleach, approximately 3 tbsp. Add the cap to the bottle and tighten. Slide the bottle into the sheet metal and add sealant around the base of the bottle. Drop bottle through the hole in the roof and allow the sheet metal to keep it in place.

In one sentence, describe what the following article is about: Transfer the grilled steak to a carving board and let it rest for 3 to 5 minutes. By allowing the steak to rest, you give the juices a chance to redistribute themselves in the meat. You will end up with a more thoroughly juicy steak as a result. Hold the steak steady with a meat fork and use your other hand to slice the meat with a carving knife.  Use a carving knife with a thin blade. Turn the steak so that the long end faces you. The muscle fibers, or "grain," should run horizontally. Hold the knife at a 45 degree angle and cut the steak across the grain. Do not cut the steak alongside the grain, since doing so will result in tough, chewy meat. Carne asada is best served hot.
Summary:
Let the steak rest. Carve the steak into 1/4-inch (6-mm) thick slices. Serve immediately.
