Not only does this Measuring Plant (the design brainchild of Ana Mir and Emili Padros) provide an aesthetically pleasing alternative to the pencil marks so many of us use to trace our little sprouts' growth spurts; with a maximum height of 2 meters, it also helps to teach the metric system. Considering that it also adheres easily to most walls or doors, the the stick-on vinyl plant makes a nice alternative to wallpaper, as well.
