With slight magnification a green rim on the top limb of the solar disk can be seen on most clear-day sunsets. However the flash or ray effects require a stronger layering of the atmosphere and a mirage which serves to magnify the green for a fraction of a second to a couple of seconds.
Rust-OleumÂ® Specialty Chalk Board Spray converts surfaces into a usable chalkboard. Apply to metal, wood, plastic, hardboard, glass or paperboard. Erases cleanly. Indoor use only. Cleans with soap and water.
Let the paint dry completely and then âprimeâ the chalkboard wall by rubbing chalk over the entire thing and then erasing it. This helps future artwork wipe off evenly (leaving no remnants behind). I recommend this DIY chalkboard paint for creating a small or large chalkboard wall on drywall.
