In passive solar building design, windows, walls, and floors are made to collect, store, and distribute solar energy in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices.[1]
[pinit] I looked on the back of a Magic Eraser package the other day and noticed there werenât any ingredients listed. That seemed very odd to me since just about every cleaning product out there has some kind of ingredient. I did a quick search and found out Magic Erasers are made of a product called melamine foam.
You can also raise the Tolerance setting to select a broader range of contiguous colors. Magic Eraser. Click the area you want to erase in your image, and select Contiguous to erase only those pixels actually touching the pixels you clicked. Deselect, or uncheck, Contiguous to erase all similar pixels in the image.
