Mass participation world records are quite popular and range from common activities like dancing to more unexpected efforts like screaming. Here are a few highlights:
* The longest human domino chain is 2,019 people. The participants used mattresses to accomplish this feat. 
* The longest head massage chain was set by 578 women. It was defined as applying hair oil and performing a specific sequence of techniques. 
* The loudest scream is currently recorded at 127.2 dBA and was set by a group of Finnish scouts.
