Bozeman fifth graders got a chance to learn about science hands-on Thursday.
It was part of MSU's Nano Days- a celebration of nanoscale science and engineering.
Montana State students and faculty, and middle school students from Headwaters Academy, hosted the nano-science demonstrations.
A nanometer is one-billionth of a meter. Nanotechnology involves manipulating particles at the molecular and atomic level, and can be used in healthcare, alternative energy and manufacturing.
Participating students from Irving Elementary said they had fun learning about the high-tech science.
"I think it's really cool that all the MSU students came out to try to teach us about nanos, and I just thought all the stations were really awesome and cool," said Charlie Steele.
