Number 2 on the most-popular-posts-this-year list is Distracting Your Toddler 101 -- an important introductory course that should be required for every student parent.

It's amazing what kids find interesting.

My second favorite post of all time is this Moon Viewer, a project I made for Kiddo two years ago. It has provided much entertainment since then.
It works by projecting the phases of the moon on the wall. all you need is a cylindrical container (think: salt) and a small flashlight. Go ahead and make one for yourself.
