Design Inspiration
A physics sweatshirt for cat lovers with ambitious plans and questionable trajectories.
One cat. One high shelf. An unnecessarily dramatic launch. Escape velocity is the minimum launch speed needed to escape a body's gravity without further propulsion, ignoring air resistance and other bodies. This cat is aiming for a bookshelf, not leaving Earth, but apparently nobody told the launch crew.
Gildan 18000 cotton-polyester fleece with a crewneck and ribbed cuffs. Machine wash cold and tumble dry low.
Perfect for: physics fans, cat people, teachers, and students. A playful gift for anyone who has watched a pet turn a bookshelf into a mission control emergency.
