Why it worked
The video likely worked due to the satisfying visual of money being dispensed from the "money guns," combined with the novelty of the product itself. The quick cuts and clear demonstration of the product's function would have kept viewers engaged.
Summary
The video showcases two different money guns, a gold one labeled "Money Gun" and a red one labeled "Super Gun". The creator demonstrates how to load them with fake currency and batteries, and then fires them, scattering money.
