Thank you so much for the gift! The markers are always needed, as well as the giant bottle of glue. We will get a great deal of use from the glue when we make slime for Halloween (polymers). The Hot Wheels tracks are wonderful for motion and force demonstrations and the glow sticks will come in handy when starting Chemistry next semester. We always have need for craft sticks when building models and the scissors will be essential then as well. My students are particularly excited about the sparklers! The next gift arrived a few days later and it was just as good. The kitchen chemistry supplies are wonderful, but the biggest hit was the new Newton's cradle. My old one had been tangled pretty badly before and wasn't working so well any more. Thank you so much!
