Try to find a place that has two stairs that you can drop off. Ride towards them with a little bit of speed. Right before you go off, drop your body lower and back a little behind the seat and push the bike forward a bit at the same time. You don’t actually pull up when you do drops. If you do, you run the risk of landing on the rear wheel first, then slamming the front wheel down after. That results in a ton of weight being transferred from back to front and can result in a theatric "over the bars" experience.
