The trick is the vape pen...

...said the lady blowing bubbles.  Husband and I took a walk along the Columbia River today, first we met axe throwing man (see Extra Photos). On the way back, axe throwing man was sitting in a tree house playing his guitar.  Further up the trail was the bubble lady standing on a bench blowing lots of bubbles.  I asked her if I could take her photo (yes) and she explained to me that the trick is using the vape pen then blowing the bubbles with the smoke blown in to the bubble wand.  She said the solution is very important also, dishwashing soap, vegetable glycerin and water.  I probably will not be trying this, I don't want to take up smoking for photography.  An interesting walk to say the least,  husband then suggested lunch outside at a little brew pub in town.  This afternoon the rain has returned.
