How long will it take my baby son to defeat the Strong Suction Silicone Plate?

We bought the QShare Strong Suction Silicone Baby Plate from Amazon. This product promises to remain affixed to any plastic, metal or other smooth surface no matter how hard a youngster tugs at it. In preliminary testing, we noticed that it was secure when pulled, but that it could be peeled up at the edges.
So after serving up Alfy's dinner and placing him in his high chair, we trained a camera on him to see how long it would take him to defeat the Strong Suction Silicone Baby Plate—if at all.
