    Irene,

    it is great to plan balloon rockets as Design & Make – children will then try an improvement, see if it works, and refine as needed.

    I have been about 15 years getting balloon rockets to work – and I find they are best for me when I make the strings vertical, with a weight (usually a roll of sellotape) holding them down.
