Curious if we all could point out what is wrong specifically. As a learning excercise. I'm thinking if you know what you are doing they all are safe. The kids could have more ppe working with alginate that you can eat?
The methanol or possibly ethanol jug doesn't have excess liquid and isnt being poured on a flame near students for example. Which is the hazard.
 Liquid n2 in hot water... it has some hazards but very little. And it was not near the kids.
H2 balloon is farther from kids than it looks.  And it seems to be just h2 as it didn't explode like it had o2 in it.  
Starch in the mouth is well.... i need to brush my teeth....
Dancing without goggles? Dry ice in water?
Too much fun?
Sorry for any snark but really curious.

I saw it last night and thought that ACS (Marta) might send her the guidelines on demonstrations. I can think of all kinds of ugly scenarios.
Stay safe out there.
