But I don't think that the explanation is correct because I think that it is the formation of both baking soda and water that makes it work...Vinegar doesn't make gas bubbles maybe because it hasn't reacted or maybe because it is not the right ingredient for the solution you are looking for. Thank you for the question.....Am not sure I really helped in your question but thank you..
It could pass by a large enough object that has enough gravity to pull the object into its orbit and the object would stay in orbit because it has centripetal force.
