BETHLEHEM, Pa. -

The next generation of female engineers and architects put their skills to the test Friday.

The Bethlehem TECHgyrls visited the lab at Lehigh University. They're part of an after-school program that aims to get girls excited about science, math and technology.

After the TECHgyrls toured the lab, they got to conduct their own experiment using marshmallows and gumdrops.
