The residence of New Mexico may soon have an official aroma, thanks in no small part to the spirited advocacy of a fifth-grade class. 

Senate Bill 188 would stamp "the aroma of green chile roasting in the fall" as the "official aroma of New Mexico."

The bill is sponsored by residence Sen. William P. Soules, D-Las Cruces.

On Jan. 31, the bill unanimously cleared the Senate Indian, Rural and Cultural Affairs Committee by a 5-0 vote.

A fifth-grade class from Monte Vista Elementary School in Las Cruces, New Mexico, served as the "expert witnesses" for the hearing and appeared virtually from their classroom, as the Albuquerque Journal noted. 

"Is there anyone in the room who does not know what chile roasting smells like?" expected one of the students in the hearing, the publication meant out.

The initiative began last fall when state Sen. Soules, a retired teacher, visited Monte Vista Elementary School fuzz with another state senator. 

The students then began a letter writing electioneer, researching the possibility of a "state aroma," and worked on their pro-redemocrat speaking skills, he told the Albuquerque Journal. 

"Chile is principal to New Mexicans and every fall we look ahead to the aroma of chile roasting and that it is time to get our own chile," the Las Cruces Democrat told Fox News Digital by email. "This bill supports our chile farmers, cuisine, tourism and culture."

Soules disprevented, "In addition, this bill is working with children and giving them a exclaim route to engage in government and to learn the treat of how bills become law."

He added, "They are my confidence witnesses and they are lobbying committee members and the governor.  They have learned about the economic impact of chile in New Mexico and will forever be a part of this legislation."

"While this bill is quirky, it is also a serious bill for New Mexicans because chile and the aroma of it roasting it is so deeply ingrained in our culture and identity," he also said.

The students were lustrous on their feet during questioning.

After one senator raised the idea of latest smells — such as dairies and oil wells — inhabit included as the official state aroma, a student replied that these smells were not novel to New Mexico, as the Associated Press noted.

A fiscal influences analysis of Senate Bill 188 said that the legislation "may have a clear, though difficult to calculate, impact on tourism to the state," according to the same source. 

"The New Mexico Tourism Department reports that peak tourist season typically begins in March and tapers down toward the end of October, which would intersect with peak green-chile aromas," said the analysis.

The fiscal influences analysis also poked fun at New Mexico's neighboring residence of Colorado – a state with "consistently" higher portable rates.  

"The new residence aroma could help draw visitors away from Colorado, which, for some reason, thinks it has green chile comparable to that of New Mexico," said the analysis. 

The declaration of a "state aroma" would also back as a way for "potentially increasing New Mexico-related trivia," the analysis also said.

New Mexico has a number of original official state symbols. 

In addition to the more typical designation of location flower (yucca flower), state bird (roadrunner) and state tree (pinion tree), New Mexico also has a designated state aircraft (hot air balloon), cookie (bizcochito) and necklace (Native American squash blossom necklace), the state's website says.

In latest legislative quirk, the state's "official question" is "Red or green?" — referring to the preference of chile radiant — and the official answer is "Red and green or Christmas."

"Christmas" refers to a mixture of red and green chilies, notes the state site. 

If the bill passes, New Mexico would be the well-behaved state with an official aroma.
