A house too small for even Tiny Tim

The Citizen (KZN) - - To Make Your Day -

Ot­tawa – There was Tiny Tim, and then the Lit­tle Drum­mer Boy – but they had noth­ing on the mi­cro­scropic gin­ger­bread house be­lieved to be the smallest in the world, un­veiled by a Cana­dian re­searcher.

About half the size of one made in France last year, it was cut and etched from sil­i­con, com­plete with sharply de­fined bricks and trim, and a Cana­dian flag for a wel­come mat.

McMaster Univer­sity re­searcher Travis Casagrande said he used a beam of charged gal­lium ions that acted like a sand­blaster.

Im­ages pro­vided by the Hamil­ton, On­tario school’s Cana­dian Cen­tre for Elec­tron Mi­croscopy showed the house sit­ting atop a cap on the head of tiny wink­ing snow­man made from ma­te­ri­als used in lithium-ion bat­tery re­search.

The pair of dec­o­ra­tions stacked one on top of the other are barely taller than the di­am­e­ter of a hu­man hair.

The cen­tre’s suite of 10 elec­tron mi­cro­scopes and other equip­ment are used mostly for ma­te­ri­als re­search.
