Benylin makes a great vapour plug-in. You (very carefully) insert a thin tab into a electrical plug-in and it scents a room with the smell of vapour rub. It is great. No mess on your skin or the kids - no fear of someone getting the rub somewhere it shouldn't be... it gets plugged in at night and then runs over night... great - bestest thing! Love this product - plus it actually smells up our living room and I love that smell... so now my living room smells like vapour rub and Michael likes it in his room - as he has a mild cold right now.
I bought this at Shopper's Drug Mart.
