For young engineers and scientists that want to get their hands dirty (or don't have a laptop or don't want to do science on a laptop) there's the tried and true book-variety of science experiments. Loved (still love) this classic put together by UNESCO: https://archive.org/details/isbn_9780385052757
Even better, the Golden Book of Chemistry Experiments: https://archive.org/details/TheGoldenBookOfChemistryExperime... Just keep an eye on the kids while they're experimenting. It's a fun read, but it includes experiments like "how to cut glass tubes", "making chlorine in the home lab", "making sulfuric acid"...
"Many of the experiments contained in the book are now considered highly dangerous for unsupervised children, and would not appear in a modern children's chemistry book. OCLC lists only 126 copies of this book in libraries worldwide. It was said that the experiments and information contained herein were too dangerous for the general public."
Wow
