How to produce fumes in chemistry lab?

In chemistry lab we perform experiments to find the unknown solution. I just want to produce some fumes in lab. We are only allowed to use few common dilute solution like $\ce{NH\_4Cl}$, $\ce{NH\_4OH},$ $\ce{HCl}$, and few more which are generally allowed to students.


Is it possible to form fumes in lab? 




Aqueous ammonia and hydrochloric acid are solutions of gases. 


In a **fume hood** place two beakers with aliquots of these two solutions (one in each beaker, **don't mix**) side to side. 


**Did I mention the fume hood?**


You'll see the formation of solid ammonium chloride from the reaction of the two gases.


$$\ce{HCl(g) + NH3(g) -> NH4Cl(s)}$$


**Don't forget to clean up the mess!**
