image: Microscope images show effervescent microneedles on a contraceptive skin patch. When applied to the skin, effervescent bubbles quickly separate the microneedles from the patch so that the patch can be removed after one minute. This material relates to a paper that appeared in the November 6th, 2019, issue of Science Advances, published by AAAS. The paper, by W.
