with the LED balloons, you get 2 watch batteries, but with a bigger battery, it won't light up. Why?
inside the little box that lights up the balloon are 2 watch batteries and an LED with two prongs, the 2 batteries are stacked so the negative terminal is on 1 prong, and the positive terminal is on the other i tried to use a bigger battery but it still won't light up. Anyone know why? or if there is another way to make it light up with a bigger battery?
