Weight boxes for 3 helium balloons
Beautiful Examples of DIY Balloon Weight Boxes, found at www.art-of-craft.co.uk
Hi, can you tell me what size weight box I would need to use for 3 party helium balloons? 🎈🎈🎈ANSWER
With "weight box" you are referring to balloon weights (also called table bases or anchors) to hold your balloon bouquet down, right?
An 11 inch helium filled latex balloon has a lifting capacity of about 0.35 oz (10 g). So the absolute minimum weight for your anchor has to be 1.05 oz (30 g).
To be on the safe side, I'd suggest to make it at least 1.76 oz (50 g) heavy. The size of your base doesn't really matter. It's the weight that counts.
You can easily make these table bases
yourself, using balloons and sand.
Or you buy a ready made weight. Here are some examples at Amazon
