Yeah I saw it by myself. I was mostly interested in the science behind the "PYM Particles" theory.

Here's something that some don't know; Rita DeMara or also known as "YellowJacket"  once stole one of Hank Pym's outfits and became the new YellowJacket. 

After a few other adventures in the Marvel Universe she ended up in the 31st century with the "Guardians of the Galaxy" (Not the movie, the comic books of course.) where she tries to redeem herself of being a "bad guy" in her past life.

Now, what was interesting about her use of PYM Particles is that not only can she shrink, however increase in size as well.

At one point in a fight with another villain who also could increase his size, she was forced to play the game; "Top This"  and become the height of over 100 feet tall which also increase the power of her "energy stings" as well and taking the guy out fast.

However, there is a price in becoming so large so fast and in her case at being a great size put a great strain on her heart. (Hey, the bigger you get the more stress you put on your body with the planet's own gravity against you.)

Lucky for her, she was able to shrink back down quickly, however it clearly shows why she rarely uses the growth ability with the PYM Particles.
