Thinking Putty (Liquid Glass)
If you buy one fidget, buy putty — and Crazy Aaron's is the one that earns its price. It stretches, snaps, tears, and oozes back into a blob, and unlike the dollar-store stuff it genuinely never dries out, so a tin lasts years instead of weeks. Liquid Glass is clear, which kids love because they can trap bubbles and watch it slowly flatten. It's quiet, it's contained (no bits to lose), and it's the rare fidget that calms a wound-up kid and occupies a bored one equally well. Made in the USA, and the 4" tin is the right size — not the tiny travel one.
