How did 'velcro' get translated to 魔术贴 ('magic attachment??') This is one of the most interesting translations i've encountered. 
The '... + 贴' pattern is understandable, but how did '魔术' (magic) get there?
The only other word I know that has been translated as '魔术 + ...' is 魔术方块 (rubic's cube), which I suppose makes more sense than trying to transliterate 'rubics'. I'm just curious as to the origin of this.
魔术贴 is not a translation or transliteration of Velcro. It is a 'Chinese name' given to the product.

Terms like 魔术(Magic) or 神奇(wonder),  are commonly used in naming new and innovated products.
