Review on 2000 Clear Reclosable 1 Inch X 1 Inch Zipper Bags By IMBAPrice by John Shitifano

Nice, sturdy, tiny zip bags! We are using them in middle school science classes for density and catapult labs so strength is important! The kids shot bags filled with water or ice from small catapults as far as 3 meters and had only one develop a leak after multiple landings. Density labs included floating and sinking hot water filled bags in ice water and the opposite. They survived all temperature changes without holes. I liked that they were so small for the labs because that allowed me to use beakers as the float tank (instead of something larger with no graduations) to help measure the how much sinking or floating occurred. If you are not doing science and want to put jewelry in these, they are very small. maybe only stud earrings or delicate rings would fit.
