Doraemon gets Nobita to focus on his homework by spraying him with a Concentration Soap Helmet. Nobita later uses the gadget on Nobisuke (to help him focus on digging a hole in the yard), Gian and Suneo (to help them focus on looking at ants), Shizuka (to help her focus on making a sweater) and other neighborhood residents. But once sprayed, they can't stop focusing what they are doing and Doraemon and Nobita have to pop the helmets before they overdo them.
