QUICK! It's not to late to make a pinhole viewer!

Tomorrow there will be an eclipse of the sun by Venus. Actually it's not really an eclipse but a "transit".  Venus is not big enough or close enough to eclipse the sun, but it appears to move (or transit) across the face of the sun.  Only you can't see it with your naked eyes because you have to look directly at the sun AND THIS IS VERY DANGEROUS.  So here's how to view the transit.

Make a pinhole viewer.  They are easy and take about half and hour and use materials you have about the house.

Here's an easy one that is specially an eclipse viewer.  Our nine-year old made it on her own.

Here's one that is a general pinhole viewer.  This you can use for viewing everything through the pin-hole and everything is UP-SIDE DOWN.  I kid you not. It is amazing.  It has easy instructions to follow as well as an explanation of how it works.

You really need to block out the light.  When we taped the boxes, we put strips of foil along the cut edges first and then covered those with masking tape.  This kept out the light much better than the masking tape alone.

Then we made a really great improvement to the pin-hole viewer.  We took a black T-shirt and taped (using strong packing tape) the bottom of the shirt around the viewing end of the box.   Then you put your head through the head-hole to the inside of the T-shirt.  Thus all the light is blocked out and you get a really good picture on the inside.

We are really looking forward to the eclipse.  Let's pray for a sunny day!

Check out this site to find out when you can "see" the eclipse. Those on the east coast of Australia should be able to view the whole transit (should it be a sunny day).
