Elinor and her friends solve a “sticky” mystery, in this latest title in the series. Ari’s cool new watch makes a skrrrrtch sound when he opens the strap, and then he can just press it closed again. Neither part of the strap is sticky, so how does it work? Elinor, Ari and Olive decide to investigate, starting with determining what else the material sticks to. While they’re searching outside, some spiky seeds get stuck on Ari’s sweater. Hmm, they make the same sound as the watch strap when Elinor pulls them off! Could they be a clue to unraveling the mystery? Curious minds will be hooked, as they learn that nature has given us some great ideas!
