  "question": "Which hands-on science kits let children experiment and learn at home?",
  "answer": "Heebie Jeebies crystal kit: The kit grows a display crystal by combining the supplied crystal powder with water. The maker recommends the kit for ages five and older.\nKlutz Make Your Own Discovery Bottles: The six named experiments are a galaxy glitter swirl, fish-through-the-hoop game, tiny tornado, lava fizzler, eye-find game and jellyfish float. The hands-on review considered the English instruction book the strongest part of this exact kit, particularly for learning everyday material names and scientific vocabulary such as density, viscosity and polarity; it also appreciated the science questions. It did not report long-term leak resistance, durability or failure points. Scholastic says this product is no longer in its range.\nHeebie Jeebies polymer snow test tube: Add water to the powder; it expands into artificial snow within seconds. The maker’s catalogue recommends ages 8+; the store recommends ages 5+ with adult supervision, so the sources disagree. The package contains one test tube with 60 g of polymer-snow powder and one instruction sheet with science facts.\nKlutz DIY Rainbow Catcher: The kit builds into a motorized machine using gears and electronic components to make rainbows move around the room. The maker recommends the kit for ages 8 and older. A 32-page instruction book is included.",
