Author: Kathy Wollard, 320 pages, paperback.
For every kid who really wants to knowโ€”and for every exasperated parent who simply doesnโ€™t knowโ€”here is a lively omnium-gatherum of explanations to the most frequently asked questions about our world, from โ€œWhy do stars twinkle?โ€ to โ€œWhat are hiccups? โ€œTaken from Kathy Wollardโ€™s popular column, โ€œHow Come?โ€ (seen for the past six years in Newsday and recently syndicated nationally through the Los Angeles Times ), How Come? explains why cats can survive high falls (because of the way their bodies can act like a โ€œparachuteโ€) and how black holes absorb light (intense gravityโ€”if the Earth had the same density as a black hole, it would have to be compressed to the size of a marble!). Now you can know it all.
