自動バブルマシン | KiwiCo

My six-year-old was obsessed with figuring out how the soapy film stretches into a bubble before it drops, and the machine just keeps pumping them out non-stop.

The motor hasn’t stalled once since we set it up, and the continuous bubble stream kept my kids entertained for a solid hour in the backyard. The way the lesson on soap and water bonds is woven into the build makes it feel less like a toy and more like a mini science win.

My nephew tore through the build in an afternoon, and the non-stop bubble stream kept the whole backyard entertained for hours. The way the instructions tie the soap-and-water chemistry into the actual mechanism made it feel less like a toy and more like a real experiment we did together.
