On Tuesday, May 22nd we had a fieldtrip with Bayou Cajun Homeschoolers to LIGO which stands for LASER INTERFEROMETER GRAVITATIONAL-WAVE OBSERVATORY. They had lots of hands-on science activities for the kids. After lunch, there was a tour of the actual observatory, but I didn't go on that part because I stayed with the younger kids.
