The Botanicalls project, created by Kate Hartman, Kati London, Rebecca Bray, and Rob Faludi at the ITP program at New York University, lets your plants call you when they need to be watered!
Botanicalls allows thirsty plants to place phone calls for human help. When a plant on the botanicalls network needs a lot or a little water, it can call a human and ask for exactly what it needs.
When humans phone the plants, the plants orient callers to their habits and characteristics, including how they like to be watered and cared for. Call 212.202.8348 to hear more about each of the plants.
Botanicalls opens a new channel of communication between plants and humans, in an effort to promote successful inter-species cohabitation and understanding.
