The day came for their performance came and after which, we ventured to the exhibit. I wasn't planning on going there that time but he insisted on going in after he saw one of his friends inside.
Plenty of things to see although way beyond his level but the fun of discovering the manipulative exhibits and running around with friend were enough to keep us inside for almost an hour.
Sad thing is my cam batt conked out and I wasn't able to take any picture except for the one below. :-(

Photo taken with my outdated phone. Unknown little girl was brave enough to try one of the exhibits.
