Students work as biomedical engineers to find liquid solutions that can clear away polyvinyl acetate polymer "blood clots" in model arteries (made of clear, flexible tubing). Teams create samples of the "blood clot" polymer with different concentrations to discover the concentration of the model clot and then test a variety of liquids to determine which most effectively breaks down the model blood clot. Students learn the importance of the testing phase in the engineering ...

Old newspapers come in handy for many different uses around the house, from birdcage liners to shipping cushioning and even a little fish cooking. But for backyard rocket scientists like Markus Bindhammer, they're more suitable as an ingredient for rocket propellant. Video: . For this rocket fuel, the old newspaper is actually the secondary fuel. The primary is polyvinyl acetate, basically just white wood glue, which also acts as the binder. The oxidizer is KClO3, aka potassium chlorate. ...
