For the last year or so, Jonah has been obsessed with #thegreatballcontraption.

People will make lego machines that pass little balls from one “module” to another and anyone can submit their own modules to use. It can end up being hundreds of modules long.

Jonah loves watching them on YouTube.

Vex Robotics has engineered a few of these designs so they can be put together independently.

So of course, Auntie and her former roommate put a couple together for Jonah.
