Here ’s an odd toy dog from Crayola that could serve as a tool , too . The Crayola Total Tools Audio Ruler set down a product line of melt ink , and then blurts out on the dot how long that argumentation is as soon as you ’re done drawing it . It ’s accurate to within a quarter of an column inch , but has a major limit .
It can only measure up to a foot in duration , which would probably turn out to be a drawback if you wanted to use this as an actual putz . If it could resolve measuring down to at least a 16th of an column inch , it might be utile for someone who ca n’t see very well . But expect a instant , blind carpenter ? It could come about , it really could . Until then , parent will long for the daylight when rulers stay soundless , mind their own business . [ Crayola , viaBook of Joe ]
