The video features an experiment where liquid metal (gallium) is injected into a Stretch Armstrong doll using a hypodermic needle. The gallium is melted down and then injected into the doll, causing its body to swell and change shape. The experimenters then refrigerate the doll to solidify the gallium and later dissect it to examine the metal's distribution inside the doll. The gallium is found to have formed geometric shapes and crystallized within the doll's body. The video also features a comparison of the doll's original state and its changed state after the experiment.
Here are the key facts extracted from the text:
1. The experiment involves injecting liquid metal (gallium) into a Stretch Armstrong doll.
2. Gallium is a non-toxic metal that melts at approximately 85 degrees Fahrenheit.
3. The gallium was melted down and cooled to around 68 degrees Fahrenheit, but it didn't solidify.
4. The gallium was supercooled, meaning it remained in a liquid state below its freezing point.
5. The experimenters used a food basting syringe and a hypodermic needle to inject the gallium into the doll.
6. The doll was filled with corn syrup, which is a thick liquid that allows the doll to stretch.
7. The experimenters inserted the needle into the doll's chest, arm, and knee to inject the gallium.
8. The gallium caused the doll to swell and change shape.
9. The experimenters refrigerated the doll to cool down the gallium.
10. After refrigeration, the gallium solidified and formed geometric shapes inside the doll.
11. The experimenters skinned the doll to reveal the gallium inside.
12. The gallium was found to be crystallized and formed a solid shape inside the doll.
13. The corn syrup inside the doll was extracted and considered for use in making cotton candy.
