Among the 750 species in residence at the San Antonio Zoo are several Mold-A-Rama machines, using hydraulic arms to press candy-colored wax into little zoological statues. Sort of a precursor to the 3D printer (with a very limited menu), these relics from the 1950s have a nostalgic and thriving eBay following for those looking to get their hands on some waxy childhood memories. At $2, they're more charming and significantly cheaper than much of the zoological fare in the gift shop, helping to keep the cost down on family trips. So after seeing your favorite exotic animal, stop by the Mold-A-Rama for a trinket to cherish forever or to sell to sad old guys on the Internet. 3903 N. St. Mary's St., (210) 734-7184, sazoo-aq.org
