Science Museum Oklahoma
A huge hands-on science museum with hundreds of exhibits, a planetarium and a high-wire bicycle you ride across a cable above the main hall. Tinkering Garage lets kids build with real tools and materials, and CurioCity is a whole floor of physics and body science stations. Live science demonstrations with explosions and liquid nitrogen run through the day. There is a dedicated area for the under-fives and a small aviation hall with real aircraft. This is a full day and the single best indoor destination in Oklahoma.
