36 is the number of circles inside recently installed solar tube diffusers
36 circles are inside each diffuser of the solar tubes recently installed at Crocker/Riverside Elementary School in Sacramento, CA.
How do we know? Maddie, a student at Crocker/Riverside, told us so! In her thank you letter, she told us “[she] counted, circles in the diffuser, there are 36. And 9 solar tubes. I like the solar tubes.”
We received 25 thank you letters from students for the new solar tubes. Take a look at their inspiring (and adorable) letters here.
