This summary via Euro Weekly News: 
A total of two adults and three children were hospitalised suffering from injuries after an explosion that occurred at Girona’s Casa de Cultura yesterday, Friday, September 30. According to a spokesperson from the Josep Trueta Hospital, they are all out of danger and could even be discharged later today, Saturday, October 1.

Eighteen people were injured when a drum of liquid nitrogen exploded during a scientific outreach event, which mixed magic and science, designed to bring science closer to children, as reported by

You can watch the various videos of the incident here, here and here on Twitter. It sounds like the demonstrator was a reasonably prominent science communicator in the Catalonia region who was fairly experienced. 

It's pretty clear this demonstration is a version of the classic liquid nitrogen/ping pong ball demo, but it is weird to me that they added a second drum with a drum lid clamp on it. The demo put one of the drums in the air, which is definitely not good. I'll withhold judgment, but it's pretty clear the crowd was much too close. Here's hoping that we get some more conclusions soon. 

Best wishes to those injured.
