I applied the principle of cutter knife. A cutter knife can control the length of its blade, and I made my compass like that. My invention can control the length of its legs, so users can put the needle inside its legs. The legs are divided in two parts, and users can put down side of the legs into the upper part. I invented this because I liked drawing figures with compass and rulars. But I always got pricked by the needle of the compass. Teacher! Thank you for having a class with me tonight. See you tomorrow, and have a good night! Annie. 답변자 ts0040 답변일 2014-02-13 답변내용 Hi! This is impressive! I think I want to have this compass too! :) It is always my pleasure to have you in my class.
