Future head of mechanical engineering

So you know those clippy elastic things that keep mittens attached to coats? Seems my child has an aversion to stuff she cannot toss to the ground. I purchased a pink pair of them last night and victoriously ratcheted them to her winter coat before we left the house this morning; all the while thinking, "There is no way in hell she will be able to open these. No way." Then in the car on the way to daycare I hear her precisely rip each one off from her purple-sleeved jacket and throw them slowly and deliberately to the floor.
I. Can. Not. Win.
