Click to read the description: I was asked to bring my funnel back out and do a weight gain shake challenge. Unfortunately, I don't have a 3-gallon blender, but I was able to get down half a gallon of it. The liquid came down so fast through the tube I forgot what a rush it was to fill up with calories so quickly. I finished all of it but a little froth at the bottom of the blender and I surprisingly wasn't too full. I definitely will bring out my funnel more often once I get something to hold it in place when my arms get too tired.
