Does what it says, not hard to do at all and the nice little covers they provide are nice compared
to the old way of creating the open can illusion. Yes you have to do some prep work that takes
maybe one minute out of view probably but if you're slick you could do around people I suppose but
other than that just as the video shows. I like this effect and can be done with any carbonated
drink, even beer etc. as explained in the video. Video is only 16 minutes long which is perfect (I
hate long hour long explanations and theory video's personally, lol) I would recommend this to a
beginner or a pro.
