Regentropfen

My two-year-old can pour water into the top for ages without getting bored, and I love that it all filters down into the clear box below so we can watch every drop collect. It's sturdy enough to survive being tipped over on the patio, and it keeps her entertained while I sip my coffee.

The way the water trickles down through each layer is mesmerizing for my 3-year-old—she'll pour it in over and over without getting bored. It's simple but somehow keeps her engaged for a solid chunk of time, and cleanup is just a quick wipe.

I was a little worried the water flow might be too slow, but my 3-year-old loves watching it trickle down through the filters. The box at the bottom catches everything nicely and keeps the mess contained.
