Preheat oven to 400 degrees.
In a large mixing bowl, pour in water, sugar, and yeast. Let stand for 10 minutes.
Mix in salt, olive oil, and 2 cups of flour until thoroughly mixed.
Add in the rest of the flour while continuously mixing until dough comes off the side of the bowl clean.
Cover and let the dough rise for 30 minutes.
Roll dough into one long tube (about ¾ inch in diameter).
Cut dough tube into seven to eight-inch pieces.
Place dough sticks on sprayed (cooking oil spray) cookie sheets, and let sit for 15 minutes.
Brush dough sticks with ½ of the melted butter, and sprinkle with salt.
Bake for 13-15 minutes until golden brown.
Mix remaining butter and garlic powder, and brush on top of breadsticks after removing from oven.
