If you want to see a proof that a hammer and feather fall with the same speed in vacuum, you can see it at 1:47 into this video
Hear them sing 'Strolling on the moon' while on the moon.

I wonder how the astronauts got the feather. Did they bring it from the earth, just for the experiment? Anyway, a piece of paper would work instead of a feather.

Here is a story about the moon feathers. I don't know what Atlas Obscura (the source of the story) is, I just hope that their story is true.

Object of Intrigue: The Falcon Feather on the Moon

"Mission commander Dave Scott brought the feather to the moon in order to conduct an experiment.

Scott had been planning this experiment for the better part of a year. In January 1971, he and fellow Apollo 15 astronauts Jim Irwin and Al Worden visited the Air Force Academy in Colorado Springs, where they met the falcons that serve as the Academy’s mascots. Because their lunar module was named Falcon, they had decided to use a falcon feather for the Galileo experiment, and collected two feathers from an Academy bird during their visit.

As far as NASA knows, the hammer and the feather are still on the lunar surface— remnants of an experiment that had its origins in the 16th century, roughly 238,900 miles away."

Another remarkable phenomenon is that a soda straw will not work in a vacuum. This is because the liquid in a straw will only move by producing a difference in air pressure between the lungs and the atmosphere.
