The Lincoln Memorial Reflecting Pool is treated with ‘nanobubbles’. What are they and how do they work?

The Lincoln Memorial Reflecting Pool now features an innovative cleaning technique using nanobubbles, tiny, invisible bubbles that are incredibly stable and thousands of times thinner than a human hair. These bubbles are being used to reduce the need for chemical cleaning agents and water, making the process more eco-friendly. This approach not only minimizes environmental impact but also provides a fascinating glimpse into how nanotechnology can be applied to preserve historic landmarks. The use of nanobubbles highlights a shift towards more sustainable and efficient cleaning methods.
