S.M.A.R.T.S. and the Invisible Robot

The S.M.A.R.T.S. can't wait for the local high school's Art of Science exhibition, which will feature student artwork made through scientific methods. It's sure to be a great show, except for one problem the centerpiece necklace has vanished! The S.M.A.R.T.S are stumped. There's no sign of a break-in, and the door to the gallery was locked. Could the jewelry really just disappear? It's up to the S.M.A.R.T.S. to solve the impossible crime. Using a combination of engineering, robotics, and some serious brainpower, Zoe, Caleb, and Jaden investigate every clue. Will they find the necklace in time for the exhibition's opening night, or will they be blamed for the high school heist?
