When we first tested air fryers, in 2017, most of the models we found were small, pod-shaped appliances that looked like they’d be more at home in a sci-fi movie than on a kitchen counter. They couldn’t hold much food, and they yielded mediocre results. If you really want an air fryer, we found that the Philips Avance Collection Airfryer HD9641/96 is better than most (though not great). But since air frying is really just convection baking, we think most people would be better off with a convection toaster oven, such as our top pick, the Cuisinart Chef’s Convection Toaster Oven (TOB-260N1), which does everything an air fryer can do, plus more.
I first built a domino row building machine of this type in 1985 out of Lego, then built it again from memory in 2009 to make a video of it. The machine works by pushing a magazine full of dominoes forward along the table while a slider pushes them out one at a time as the machine slowly drives along.
