Having a hobby denotes a person's passion, regard for mental well-being, and respect for life's little things, such as miniature sailboats full of teeny ice-cream cones made from wood glue. Feed your mind with today's Groupon: for $10, you get $20 worth of hobby supplies, games, and crafts at HobbyTown USA. This Groupon is good at HobbyTown USA's locations on Castleton Corner Drive and U.S. Highway 31 in Indianapolis.

Inaugurated in Lincoln, Nebraska, in 1980, HobbyTown USA now feeds the habits of hobbyists in 43 states, immersing shoppers in a model-toy store and art-supply shop with a science-fair vibe. Crafty options abound for many ages and interests and range from 1/25 scale 1969 Camaro model kits ($19.95) to easy-to-care-for ant farms ($15.49). Guests can spicy up routine barbecues with outdoor activities such as flying Turbo Jet 2000 gliders ($4.99) or kites shaped like 3-D space shuttles, which, unlike real space shuttles, serve decent in-flight meals ($19.99). For rainy days, pick up a 10-piece carving-knife set ($4.95) and an eight-color all-purpose paint set ($12.15) to repurpose any banister as a totem pole of achievement.

Many of HobbyTown's employees are also hobbyists themselves and, as such, will happily guide visitors through the store's many diverse departments. Shoppers can pursue their penchant for whittling or wassailing with a walking king-crab robot or simply whet their appetites with an amateur chemistry set.
