Look at the two pictures below and find the differences!
Don't touch those sea urchins below ... some are poisonous
I got stung by the first and
third and I had some seriously itchy fingers for a while LOL
(how about creating some sort of sea urchin puzzle? hmmm... flashing ideas coming to my brain!)
And the best for last... POOL-SOLVING!!!
Trying to solve a square one, while keeping afloat is not
an easy task!!!
Well, I had to do it in the pool! If I have done it on the reef I would be stung again by those vicious sea urchins!
And I am not cheating... i.e. stepping on my toes... I have actually stoppped swimming to scramble it for the next solve!
Next conference is in San Diego between 13 and 15 December... anyone staying in San Diego and wants to meet?
