My kids and I loveSkyGuy!  The video production is excellent, we love getting to see or hear from REAL kids (and sometimes their cats!) with REAL questions.  We like that the answers are provided with enthusiasm, wonderful graphics, and simple language, with encouragement to wonder and to research further.  This is one of the best educational podcasts we&#39;ve seen, and we wish there were more of them.  Thanks, Tom!

We want MORE SkyGuy!!

My seven year old son is a bit of scientist so it&#39;s to be expected that he would love your podcasts.  The fact that my five year old daughter also loves them is a credit to how great they are.  Wonderful job!
