Children of all ages and their adults are invited to come to the Altus Public Library on Saturday, April 28th, from 10:30 a.m. until 4:00 p.m. and get “Ready for Take Off!” Children will learn about lift, thrust, drag & gravity with supplies and equipment provided by the Oklahoma WONDERtorium’s Museum Beyond Walls program. Participants are invited to come and go, or come and stay, throughout the day to participate in these free hands-on activities that will encourage them to explore, design, build and create! This month the children will test theories of physics as they create a variety of paper airplanes and test them on the Wondertorium’s electric paper plane launcher! The program will close between 12 and 1 p.m. for lunch. Please call the library at 580-477-2890 for more information. This program is free and open to the public.
