What we learned is that while the thinnest cards were the most sharp (made with actual razor blades) that the thickest card (made with 1/8inch steel) was by far more effective at piercing the ballistics gel. We’re assuming this was due to overall greater force due to the card having more mass. — — — — — #science #sciences #scienceart #sciencefacts #edu #educational #education #stem #steam #experiment #experiments #nickuhas #throwingcards #cards #razor #razorblade #razorsharp
