Demonstration and explanation of the irreversible reaction of adding water to Alka Seltzer tablets in a volcano model.
Good sound in this. We’ve had a whole bunch of films this year using variations on this reaction, in a volcano model; the quality of the sound, and the confidence of the performances, make this one stand out.
However, it’s slightly tricky to spot the decent sound through the slight nausea one develops from all the zooming in-and-out. Remember the basic rule: if you’re recording, leave the zoom where it is. If you need to see something in more detail, either move it towards the camera, or move the camera to it.
That aside, this is a decent little effort. My only real concern is that I prefer to see this demonstration done with lemon juice or vinegar and bicarbonate of soda. Most people use Alka Seltzer for it because it's much more convenient, but really — it’s playing with medicines, isn’t it?

It was a fantastic and amazing film, but the camera was a bit unclear at times. Nice health and safety instructions though!

It was a good video. One little thing, sometimes the picture it a little unclear because of the fact that the camera is being held (and not on a stand) Apart from that, it's really good. BTW, I'm impressed that you can pronounce the word beginning with A!
