"Want to observe the Friday 10 May 2013 Solar Eclipse safely but don't have access to a specialist solar filter for your telescope or binoculars? I have prepared a solar eclipse pinhole viewer which you can freely download and use to indirectly observe the eclipse. I have included on the viewer information on start, mid and end times for the eclipse for the following cities: Adelaide, Brisbane, Sydney, Cairns, Perth, Melbourne, Canberra, Hobart, Darwin and Townsville."

"Poplocks are a very clever system for making movable papercraft fastenings with die-cutting and folding. The Paper Pose-Ables site has a bunch of downloadable papercraft toys you can print out and make, as well as pre-cut/scored kits you can buy, for making fabulous poseable robots and other cool figures. .. the Poplocks system really makes for a great, semi-rigid joint for the toys."

"This particular algal species, commonly found in polluted water, is often referred to as "pond scum". As the movie switches to a 20x lens and then the 40x, watch closely, toward the center of each cell in the strand, for the cell nucleus. It's right near the middle and shows as a round object that is near transparent, but once you see it, you will see others. "
