On June 28, 2014, iPLEX planetary scientists sponsored several activities at the TwentyWonder charity event held in Echo Park in Los Angeles. The 21+ event, part smorgasbord for the mind and part roller derby, included a variety of exhibits ranging from comedians to musicians to scientists. iPLEX volunteers brought an inflatable planetarium and ran shows throughout the evening and also set up a gravity well demo. Proceeds from TwentyWonder went to benefit the Down Syndrome Association of Los Angeles (DSALA) – to find out how to donate, visit their website.
