“Please Don't Startle the Robot” — Unisex Oversized Heavyweight Crewneck T-Shirt

Boxy oversized fit with dropped shoulders and a wide chest; sizes M to XL. 100% cotton heavyweight jersey, 9.1 oz/yd² (310 g/m²).

Design story & product details

The one open stretch in this crowded glass shop is the air between a steel robot hand and the curved cradle below, where molten glass pours in a bright orange arc. One flinch and that pour goes everywhere, which is the whole joke behind the stencil warning, Please Don’t Startle the Robot.

I’d buy this men’s oversized heavyweight tee for the glow. The furnace, the small glass bulbs and the stream share one hot orange against steel blue. It’s a great gift for a robotics teacher.
