DemolitionRanch's Matt Carriker conducts an experimental physics demonstration, testing Newton's Third Law by attempting to propel a kayak using the recoil from various firearms. The experiment progresses from 9mm handguns to .50 BMG rifles, showcasing how increased caliber and sustained fire generate more significant boat movement. This engaging video highlights practical physics principles through a unique, high-octane approach to firearm testing.

Quick Summary

The recoil from firearms can indeed propel a kayak, illustrating Newton's Third Law. While small handgun rounds offer minimal effect, sustained fire from larger caliber rifles like the .50 BMG or an AK-47 generates substantial movement. The AK-47 with coupled magazines proved most effective for consistent propulsion in this experiment.

Frequently Asked Questions

Can you really paddle a boat with bullets?

Yes, the recoil from firearms can propel a boat, demonstrating Newton's Third Law. While a single 9mm shot has minimal effect, sustained fire from larger caliber rifles like the .50 BMG or an AK-47 can create significant movement, effectively 'paddling' the vessel.

What is the most effective firearm for propelling a kayak with recoil?

Based on the experiment, sustained rapid fire from an AK-47 with coupled magazines provided the most consistent and fastest propulsion. Larger caliber rifles like the .50 BMG also demonstrated substantial movement due to their immense recoil energy.

How does caliber affect kayak propulsion from firearm recoil?

Larger calibers with more powder and higher energy, such as the .45-70 Government, .338 Lapua Magnum, and .50 BMG, generate significantly more recoil than smaller handgun calibers like 9mm or .44 Magnum, resulting in greater boat movement per shot.

Does a muzzle brake affect kayak propulsion?

A muzzle brake is designed to redirect propellant gases to reduce felt recoil. While not explicitly quantified in this experiment, the redirection of gases could potentially alter the net force applied to the kayak compared to a firearm without a brake.
