🔥❄️ The spring that works both ways—heat it up, cool it down, and watch the magic unfold!
This 2-way Nitinol shape memory alloy spring expands when heated to 60°C and contracts when cooled to 30°C, exerting force in both directions. With a precise 0.7mm wire gauge and 9mm diameter, it offers reliable thermal actuation in a compact 1.28g form factor. Ideal for innovative demonstrations and interactive projects, it showcases cutting-edge smart material technology.

Kinda novel, but doesn't really keep it's shape
After deforming only a few times, when put in hot water, it only goes mostly back to original shape...
