Luke's Uncle Gene (Mr. Eugene McDevitt) kicked off our "Spotlight on Science" weeks with a memorable presentation on his life in the opal business. He not only mines the opals in Queensland, Australia, but cuts, polishes and markets them. We learned about the hazards of living in the bush with minimal creature comforts among some pretty strange and highly dangerous creatures. Opals can be highly varied in appearance and price.
Here's Uncle Gene explaining how veins of opal material are found in other rock. Notice the jackhammer on floor as well as samples of polished and rough opals. Uncle Gene used a power point slide show and then answered great questions from most of the students. Check out Uncle Gene's website.
