3 Perplexing Physics Problems

The video explores three physics problems: why shaken carbonated drinks explode, why ice cubes melt differently in freshwater and saltwater, and a physics trick involving a chain and ring. It explains that shaking a carbonated drink introduces nucleation sites, causing CO2 to escape rapidly, leading to an explosion. The ice cube experiment shows that freshwater allows faster melting due to density differences. The chain and ring trick demonstrates how slight rotation can lock the ring onto the chain.
