California Academy of Sciences: Science @ Home - Paper Cup Planetarium

The Academy’s planetarium may be closed, but you can still see stars! Project an assortment of mini-constellations onto your wall at home.

Listen to instructions

Using paper drinking cups, pre-made patterns,
and a push-pin, you can make your very own
projections of night-sky constellations!
Please note: This activity requires a little
assistance from a caregiver
