Transit of Venus - It's Not Too Late!
Tuesday, June 05, 2012
Smitty: "Speaking of geeked...gonna make a Transit of Venus viewer?"
Bob: "Too late. Its tomorrow. I will hold off until 2117."
No! It's not too late!
Smitty's guide to a field-expedient Transit of Venus viewer:
Method 1:
- Buy 2 of those triangular post office picture shipping tubes
- Tape them together to make a 6' tube
- On one short end, cut a hole a few inches big; this will the the "top" you'll point at the sun
- Tape some tin foil over that hole
- Pick the tin foil in the middle with a push-pin
- down near the bottom, but not on the bottom, like along the side near the bottom, cut open a window about as wide as one of the sides of the triangle shipper, and several inches long up the length.
- put a piece of blank white paper in the window and flat on the bottom
- Point the viewer at the sun
- Observe through the window!
- Take a piece of paper or posterboard and punch a hole in the middle
- Lay a blank piece of paper on the ground, maybe at an angle depending on the angle of the sun
- Kneel or stand up.
- Hold the hole-punched sheet over the one on the ground so it covers with a shadow, save for a little prick of light (I said "little prick"...I know...)
- That little prick, if pointed right, is the sun. Look for a dot. That's Venus.
Here's my source for methods 1 and 2.
No excuses! SCIENCE!!
