I will try to make them both ways, the ballons are just a heavier rubber than the general ones. You can definatly pass this on, I thought it was a great idea and super for carring in the luggage. I may even make some for the GK to store in the RV. I only have a 9 days to make as many as I can, the lady who was going to make them had an emergency come up. I guess I can play with them to test out the weight! Thank you all for your replies!!!
