Review on 🔬 Physics Fun Marble Add-On by Marble Genius by James Wonsley

Well we have several components from this brand and they are all extremely fun. I wouldn't recommend a marble run for kids under the age of 7 unless you plan on helping them, but we'll put the merits of a marble run aside for a moment to talk about THIS particular set of tracks, or more specifically rails. you suck Balls (most balls, not just a bad/small ball or two, just sink through the ground at corners and when they don't, slowly stop when pinched) or wedged between the "rails". , since they were large enough to avoid the demise of their fellows. But of course if they stay in place, that means they become a blockage, eliminating any possibility of a lucky bullet getting through. Protect your pool patience, save money and avoid disappointment. Don't take those rails and stick to the standard hard floor.
