Gross Science

Kids who love “gross” things are often secretly budding scientists; the trick is channeling that fascination productively. The National Geographic Gross Science Lab kit leans into slime, smells, and other icky experiments while still teaching real chemistry and biology concepts. It typically includes materials for multiple projects plus a guide that explains the science behind each activity. Parents like that kids are genuinely excited to follow instructions when the payoff is gloriously disgusting. It’s ideal for roughly ages 8–12 and works well as a special-occasion box or unit-study anchor. As you’d guess, it can get messy and may include content (like fake snot) that some adults find off-putting, but that’s part of the appeal for many kids. Pro tip: lay down a plastic tablecloth and wear old clothes, and have your child explain the science to another family member after each experiment to cement learning.
