Liquid Solder--Does It Work? (4K)

Two different types of conductive liquids. Between the both of them, they cost as much as a soldering iron and roll of solder! The copper one is less expensive. They claim to be for creating and/or repairing electrical connections. One is a thin copper based mixture, the other is supposed to be silver nano-particles. I always wanted to test them to see if the are a viable alternative to soldering, especially with small or delicate parts.
