A Hammer and a Feather is the first half of the fortieth episode of Ready Jet Go!.
Sydney shows Jet and Sean a cool experiment - dropping different items from the same height to see which reaches the ground first. That reminds Sean of a video he watched of an astronaut on the Moon dropping a hammer and a feather from the same height. They reach the ground at the same time. And the reason is atmosphere - or lack of it - on the Moon. Jet laughs - really? Wait, what's atmosphere? Well, the kids know the best way to find out - into the wagon/saucer! Our kids and Celery fly to the edge of the Earth's atmosphere to learn what it does... and then go to the Moon. Is the atmosphere around the Moon the same as the Earth's? And what happens when our kids do the hammer-feather drop on the lunar surface?
- Error: Sean says that they used the Scientific Method in this episode. They sang a little bit of the song, but they didn't actually perform the steps.
- Along with Commander Mom, this is the season 1 finale of Ready Jet Go!.
- Celery is revealed to have super strength, because she was able to lift up the saucer with one hand.
- The reason why the items that the kids dropped off of the treehouse railing didn't hit the ground at the same time was because of air resistance. And the moon has no atmosphere, so everything hits the ground at the same time.
- A clip from this episode is used in an Amy Mainzer Role Models segment on PBS Kids.
