In fourth grade, young chemists study the makeup of different kinds of matter. Here's a scientific experiment that demonstrates the structural principles of polymer strands, which stretch the boundary of our definitions of liquid and solid.
That's the technical explanation, of course. If you do this experiment at home, be prepared for an even more immediate pleasure: roars of laughter and gasps of delight.
What You Need:
- Several thin bamboo barbecue skewers
- Small dish of vegetable oil
- Large latex balloon
