These constructable DIY Drinking Strawz are pitched at adults, but kids would love ’em. I can see lots of fun to be had with making kid-legal "mixed drinks," but also some potential for early childhood tinkering and water play. With the right-sized rubber corks (like those used in homebrewing) you could even make multi-stream water guns with an easily-squeezed plastic soft-drink bottle as the water supply.
