I have been researching making a rocket with an engine cluster. I see a "burn string" mentioned several times as a precaution against the rocket lifting off without the main engine lit. But I cannot seem to find pictures of a Burn string.
Could you help me understand how it would be attached to the rocket and to the launch pad and what material it should be made from?
Thank you.
