My older brother, Damo should have his own version of The Curiosity Show (remember that one that was on in the afternoons?). Conversations with him usually flirt around constructions of flying foxes, the strongest magnet in the world & magnetic water, laser pointers that can be seen from space, drills with super fast speeds etc.
His latest find is the Blackwing pencil. Oh how I want some!! Check out wikipedia for definition and history. I love his continued fascination with slightly scientific, mostly kid-like glee of unusual things. When we were growing up he loved to construct bombs & blow up letter boxes, build bike ramps & get airbourne on blind corners as we patiently & confidently lined up in rows for him to fly over. I should send him to the Brooklyn Super Hero and San Francisco Pirate Supply stores. These pics were taken by Damo with his Macro lens and Canon 5D!
