This is a mechanically simple technique you can use to surprise people, if they're being lazy with their arms. From a double sleeve grip, you are aiming to cross their arms over. Sometimes you may be able to just pull them over, but you can also get them to help you by pulling their arms apart. The natural reaction is to resist by bringing the arms together, which is when you can switch directions to cross them over.
Fling your legs up high, right up over their shoulders. Lock that in place, squeezing hard. You need to have the pressure above their elbows in order to get the necessary leverage. When you have that squeezed in, you can simply pick an arm and pull on the wrist, in the direction their elbow is pointing. Be careful on this, as they won't be able to tap easily: listen out for them saying 'tap', or using something else like their foot.
Teaching Notes: On the technique, cross and clamp worked pretty well. I'll emphasise lifting the hips more, as that gives you more leverage for the armbar. Also, it's important to listen closely on the tap, they have nothing left to tap with!
People were still having trouble with those armbar drills, so I need to keep working on how to make them easy to understand. It's easy to confuse the legs. On the swinging armbar drill, the non-armbar leg pendulums into the hip, use that momentum to swing the other way, then lift your hips. Also, there is a slight push with your other thigh. On the climbing armbar, once the leg is over their shoulder, that's the side you're armbarring. The other leg digs into their armpit.
