What’s the best part about dominoes? Knocking them over, of course! Stacking them up in the first place takes time, patience, and a level of self-control that only a proportion of the population possesses! The ChooChoo™ Automatic Domino brick Laying Train will take the pain and time out of that entire process. Just fill the domino brick cartridge with the bricks, place it into the top of the train, and press the start button. The train will then start to move forward and drop bricks intermittently behind it. The bricks will be spaced perfectly apart to be knocked down!
