National Aquarium in Baltimore reopens rainforest exhibit after replacing glass roof

The National Aquarium reopened its tropical rainforest exhibit Tuesday following a monthslong closure for the replacement of its massive, 684-pane glass roof. The glass panes were as old as the aquarium itself, which opened 41 years ago, and aquarium officials say the new glass brings a host of benefits for animals — both inside and outside of the aquarium. The new, etched panes will help control temperatures inside the exhibit for plants and animals and minimize the number of migrating birds that inadvertently strike the glass. Workers also added LED lights to the top of the pyramid structure, capable of turning blue to represent the aquarium, or purple and orange for the Baltimore Orioles and Ravens.
