Actually, the foam is essential to drink a good beer, because it protects the beer from the process of oxidation, that starts if the beer stays in direct contact with oxygen, causing it to taste and smell metallic
@Taras: The gadgets I liked in this video were the scramble inside the eggshell, the tortilla toaster and the first can opener you showed. I think that jar opener would work great for disabled, handicapped and people with severe arthritis. The other jar opener would be too difficult for a disabled person to use. Really enjoyed this video. Thank you for sharing.
Sure the jar openers are large but they are for people who have very low hand grip, weakened hands, missing fingers or missing arm etc. So they Can open jars without help, and that is awesome! My father had only one hand so I can see the usefulness of such items.
