Quench Your Thirst at the Koshland Science Museum

As you explore the sights and sounds of downtown Washington, D.C., sometimes all you need is a cool drink of water. The Koshland Science Museum can be your oasis! Stop in anytime to refill your water bottle free of charge. We even have a dog bowl out for thirsty canine friends.
We want to be a good neighbor and do our part to keep plastic bottles out of landfills. While you’re refilling, pick up a free CD featuring our exhibit Safe Drinking Water Is Essential to explore drinking water issues around the globe.
There is no admission charge for filling up a water bottle. If you decide to stay awhile, admission is $7 for adults and $4 for students and military IDs.
This initiative is part of a partnership with TapIt™ and D.C. Water. Visit or download the TapIt app to find free water anywhere in the city.
