Finally another post in a series of Duplo applications. My daughter found a marble, quite a small one. Yesterday I got some utility out of it. Duplo doesn't really have smooth surfaces that makes for good tracks, until you put them on their sides. And some abstract art by a three year old to top it off.

Basic tower marble track

Drop a marble in the top and, like with certain prepared marble tracks, it ends on the bottom. This is an ugly 'functional' thing, here's some more pictures where you can derive the implementation a bit easier.

Put a marble in the top, somewhere where there's a hole or gutter, and it will come out at the bottom at either of two ends, somewhat randomly. I got lucky here, the marble and Duplo sizes and the gravitational constant on Earth in this universe come together to create this 'perfect storm' where the marble doesn't always end up at the opposite, or the same side. Which makes for a lot of laughs from my kids. (The 4 year old understands the idea easily already, the 3 year old seems to not notice yet but laughs anyway.) The 'fun generator' in full scantily clad glory:

My 3 year old made some awesome art and explained it to me, which helps me in adding captions.

Yes, it is a dog



A while back I made a different marble game. A wall of Duplo with various sized holes in the bottom, for the kids to try to roll the marble through. They have difficulty keeping attention but it does work and they get it. No pictures though but the idea is more obvious.

A was hoping I could activate the Duplo siren lights I got by letting the ball roll against the button, but it doesn't budge And Duplo lacks the means of implementing a reliable lever as a force multiplier.

I would have never guessed that was a dog. A giraffe maybe.

Or perhaps I'm not as artistic as your daughter

Your kids, sir, have far more Duplo than I ever did.

While I'm on the subject, and if crossovers are allowed, you can "convert" between Duplo and Lego by means of 2x2 Lego blocks, which fit nicely on each Duplo "bump". Trying to build Duplo on top of Lego is harder though. The point of that is, maybe you can get a Lego lever to work?

Yes I know But we have another baby on the way so I'm not too sure on introducing lego now. Or perhaps when the girls can clean up their toys better. (haha .. ha, IF they ever do)

I should draw a mockup set of technic duplo and spam Lego headquarters. It's stuff I would buy, and I assume plenty of other fathers who grew up with lego themselves.. right?
