    You need a light source and something to block it.

  3. How is light made?

    The answer is that light is made up of little tiny massless particles called photons. Photons are basically just little tiny bits of stuff that fly through the air in straight lines.

    I found out from:Ask the Van website

  4. What are sunspots?

    Sunspots vary in size from what appear to be small specks on the sun's surface, to at least 90,000 miles long, and 200,000 miles in length, and are visible on most clear days.
