{"product_id":"optical-illusion-tricks-and-toys-book-erichard-churchill-9780806968698","title":"Optical Illusion Tricks and Toys","description":"Optical illusions are tricks your brain plays on your eyes. The ones in this book move around, jump up and down, float and spin, curve, twist, and leap at you - or at least they seem to. The book provides instructions on a range of magic tricks, puzzles and toys, ranging from making your finger float and putting a whole in your hand to making moving pictures out of still ones.","brand":"WoB","offers":[{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":49577039757585,"sku":"GOR005060891","price":10.0,"currency_code":"USD","in_stock":true},{"title":"US \/ GOOD \/ SBYB","offer_id":49953069662481,"sku":"CIN0806968699G","price":3.88,"currency_code":"USD","in_stock":true},{"title":"US \/ WELL_READ \/ SBYB","offer_id":50031921987857,"sku":"CIN0806968699A","price":3.49,"currency_code":"USD","in_stock":true},{"title":"US \/ VERY_GOOD \/ SBYB","offer_id":50591083954449,"sku":"CIN0806968699VG","price":4.14,"currency_code":"USD","in_stock":false},{"title":"GB \/ GOOD \/ INTERNAL","offer_id":52108511740177,"sku":"GOR005170062","price":10.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0806968699.jpg?v=1750746382","url":"https:\/\/www.worldofbooks.com\/products\/optical-illusion-tricks-and-toys-book-erichard-churchill-9780806968698","provider":"World of Books ","version":"1.0","type":"link"}
