>> ♦Build a pinhole camera.

>> ♦Use a welding helmet and/or lens to look directly at the sun.
>>     -If you don't have a welding helmet, you can go to Lowes, Home Depot,

>>     -You need to use at least a shade #14 or higher lens

>> Observations of Venusian Solar transits were one of the earliest methods

>> Personally, I'm super excited, and I hope y'all are too!
