egglings. In this picture the role of fingers is played by various Chapsticks.
The egglings are porous ceramic eggs with dirt and seeds inside. You tap the top of the egg to break a hole in it and then water it. If all goes as it should, we should see phlox, lobelia, mint, and a petunia growing from the eggs pictured here. Tim also got one -- thyme -- but he was at work, so his hasn't been done yet.
