To get that bakery smell throughout your home, just gather your light bulbs and some vanilla extract. For best results, use an eyedropper and place one or two drops onto each light bulb, then insert them back into your light fixtures as normal. Another option would be to soak a cotton ball in your vanilla extract, then rub it all around the largest part of the bulb. This will also prevent any of the liquid from dripping off the bulbs if you have ceiling fixtures instead of lamps.
When your lights are on, the electricity results in the light bulbs heating up to high temperatures — anyone who’s ever tried to remove a recently working light bulb can attest to that. The heat interacts with the vanilla extract, releasing its signature aroma into the air. The only downside is that the vanilla scent won’t linger nearly as long as your bulbs will last, so you’ll likely need to reapply whenever you want to revive that lovely bakery aroma throughout your home.
