Commander David Scott performed the “hammer and feather experiment” on the Moon during the Apollo 15 mission in 1971.
The objective of the “hammer and feather experiment” is to demonstrate “that all objects in a given gravity field fall at the same rate, regardless of mass (in the absence of aerodynamic drag).”
After returning to the LM’s location, Scott performed an experiment in view of the TV camera, using a feather and hammer to demonstrate Galileo’s theory that all objects in a given gravity field fall at the same rate, regardless of mass (in the absence of aerodynamic drag).
He dropped the hammer and feather at the same time; because of the negligible lunar atmosphere, there was no drag on the feather, which hit the ground at the same time as the hammer.
Mission Controller Joe Allen described the demonstration in the “Apollo 15 Preliminary Science Report”:
A heavy object (a 1.32-kg aluminum geological hammer) and a light object (a 0.03-kg falcon feather) were released simultaneously from approximately the same height (approximately 1.6 m) and were allowed to fall to the surface. Within the accuracy of the simultaneous release, the objects were observed to undergo the same acceleration and strike the lunar surface simultaneously, which was a result predicted by well-established theory, but a result nonetheless reassuring considering both the number of viewers that witnessed the experiment and the fact that the homeward journey was based critically on the validity of the particular theory being tested.

On the Earth it requires specialist equipment to accurately replicate the lunar “hammer and feather” experiment in a laboratory because of our thick atmosphere and rapid gravitational acceleration of 9.81 m/s2 – 32.2 ft/s2.
The principles demonstrated by this experiment were very important to Commander David Scott because his “homeward journey [from the Moon] was based critically on the validity of the particular theory being tested”.
Therefore, in the interests of science, let’s simulate the “return journey” of Apollo 15 to Earth through low gravity space so that we can experimentally test the hypothesis that “all objects in a given gravity field fall at the same rate”.
Luckily, the Apollo 15 “return journey” experiment can be easily performed in your kitchen for an investment of less than two Euros. In fact, this budget is sufficient to simulate two simultaneous Apollo 15 “return journeys” in the experiment.
The first step in our experiment is the construction of two identical Apollo “command modules”.
The two “command modules” are constructed using:
1) Needlework thimbles for the main body of the “module”.
2) Sand and Rice for the two separate “payloads” placed inside each “module”.
3) Sticky-back pads as “heat shields” which secure the “payloads” into the “modules”.
The completed “command modules” ready for their return journey through space.
The volume, size and shape of the “command modules” are virtually identical.
However, their “payload” masses are different [sand versus rice] and, therefore, the density of the “command modules” are different.
The second step in our experiment is to simulate a “low gravity space environment” for the return journey of our “command modules” towards Earth.
The “low gravity” space environment is created simply by filling a glass jug with water. The viscosity of the water resists the downward pull of gravity [equally] for our two identical “command modules” while the mass of water displaced by the identical “command modules” provides buoyancy [equally] which also helps to simulate a low gravity space environment.
Although this low gravity space simulation is not perfect it should be sufficient to experimentally test the hypothesis that “all objects in a given gravity field fall at the same rate”.
Placing the jug of water above a globe is pure “window dressing” to aid visualisation.
The experiment is now performed by simply submerging the “command modules” before releasing them simultaneously on their “return journey” to Earth.
Observing the “command modules” travelling through the simulated “low gravity environment” clearly demonstrates that the “command module” containing the heavier sand “payload” accelerates more rapidly than the “command module” containing the lighter rice “payload”.
Therefore, the experiment indicates that the hypothesis [that “all objects in a given gravity field fall at the same rate”] has been falsified. Ideally, the experiment should be repeated with more precision under laboratory conditions. However, given the scale of the discrepancy observed in this kitchen experiment it seems very unlikely that a different result will be observed.
This experiment is not totally conclusive but it very strongly suggests that the mainstream hypothesis is false. The mainstream experiments which focus upon the “hammer and feather” introduce totally unnecessary complications into the process.
The experiment does not have to be performed on the Moon.
The experiment does not have to be performed in a vacuum chamber.
The experiment should [simply] be performed using identically shaped objects [with equal aerodynamic drag] of different densities.
Perhaps the most pertinent conclusion [for terrestrial based life forms] is that the “hammer and feather” experiment performed on the Moon [and in vacuum chambers] are [at best] an intellectual distraction [misdirection] in the real world [on Earth] where “nature abhors a vacuum”. When it comes to interplanetary space I have to choose between the integrity of mainstream science and the experimental results observed by my own “lying” eyes.
