This is a plinko machine made out of Knex I constructed in about a week that brings the balls up to the top over and over again with the help of chain lift. It even has custom score baskets and the video even includes a five-turn game, where each kind of ball (black/white and yellow) will go five times. This makes a great inexpensive way to play Plinko at home so as to everything involving Knex. Close-ups and pics of the machine are included also!! Hope you like it!!
