Flashpoint Weight Sand / Water Bottle Bag Holds 4-Water Bottles Holds 10 Lbs. Shipped Empty. Review:
Being a Theatre Tech, I've been around sand bags for years. This bag is unique in that it's designed to hold 4 bottles. I found that 24oz. Pepsi bottles filled with sand fit perfectly. While it would be OK to use water bottles, or Pepsi-filled bottles, liquid does not weigh as much as sand does. I bought a 50lb. bag of sand at [@]for less than $4, and have filled 16 bottles for my 4 sand bags, and probably have enough for the 2 additional sand bags I'm ordering today. I would not use water bottles though, as the plastic is too thin & could rupture.
