When it comes to achieving bouncy, cascading curls, curling irons are considered to be something like magic wands for hair rituals. It’s usually your go-to, right?

Well, there’s a new curling hack in town that is sweeping social media accounts all over the internet – and world. No curling iron. No flat iron. No overnight tricks. But what it does entail is a plastic water bottle and 5 minutes of your time.

Called the “#blowthebottle” challenge, Instagram users are blow drying their hair inside of water bottles to get lustrous curls. It’s even been tested out by a few salon experts.

How do you do it? Cut out a hole in the side of your water bottle that is large enough to fit your dryer’s nozzle. Slip your hair through the top of the bottle (cut it if you need to) and blow dry on a low to medium setting. Using an attachment on the dryer will concentrate the heat and prevent the hair from being sucked into it.

Pro stylist Olivia Smalley, seen here, suggests misting the hair with water and/or using a thermal protectant hair product on clean, dry hair along with this technique.

To avoid becoming a trending hashtag for #blowthebottle fire or fail, watch the heat setting on your dryer and use a bottle made of thicker plastic. If you decide to try this one, you don’t want the bottle to melt or combust.

Or, you can just continue using a curling iron or heat-free curling option like one of these.
