Looking for alternative methods to add vent to a Proton Pack

Equipment Proton Packs
1

I am moding a Spirit proton pack and want to add a vent effect. The problem I am facing is the generation of the smoke. The tried and true method is to use an E-Cig, but I am not at the right age to own one, nor do I feel comfortable doing something illegal. Is there any alternative ways to add it?

The MicroFogger might be the next way to go. It’s $100+ dollars USD but cheaper than taking up smoking. It also has a remote control so you can fog it up whenever you like.

Alternative: stand outside the 711 and asking some cool adults to buy you a vape.

Thanks for the suggestions, The microfogger seems to be the best choice so I will look into it.
