게 만지다

touch or handle it like this

All eight lines pair 만지다, to touch or feel with your hands, with either like this or how: touching the roof of your mouth with your tongue, touching a dinosaur's leg, wanting to touch someone's cheek, asking how you are meant to touch it. That is because the phrase belongs to demonstration, with the speaker showing the motion while talking. 만지다 is touching on purpose; 닿다 is merely making contact.

Register: casual, demonstrating on camera
