Wouldn't this make a great present for a curious little kid? The Eggling Crack & Grow is a sweet little porcelain egg that is also a planter. You tap a little hole into the top of the egg, pour in seeds and water, and voila: up comes your basil (shown here) or one of the other available spices or plants. Mom's little helper can contribute the main ingredient for a nice pesto! Available at Oompa Toys for about $10.
