[[Silly Putty]] and similar materials are composed of silicones [[siloxane|dimethyl siloxane]], [[polydimethylsiloxane]], and [[cyclopentasiloxane|decamethyl cyclopentasiloxane]], with other ingredients.  This substance is noted for its unusual characteristics, e.g., that it bounces, but breaks when given a sharp blow; it will also flow like a liquid and form a puddle given enough time.

Silicone "rubber bands" are a long-lasting popular replacement refill for real rubber bands in the 2013 fad "[[Wonder Loom|rubber band loom]]" toys at two to four times the price (in 2014). Silicone bands also come in bracelet sizes that can be custom embossed with a name or message. Large silicone bands are also sold as utility tie-downs.

[[Formerol]] is a silicone rubber (marketed as [[Sugru]]) used as an arts-and-crafts material, as its plasticity allows it to be molded by hand like modeling clay. It hardens at room temperature and it is adhesive to various substances including glass and aluminum.<ref>{{Cite web|url=https://sugru.com/pdfs/tds.pdf"|title=Formerol/Sugru technical data sheet}}</ref>

[[Oogoo]] is an inexpensive silicone clay, which can be used as a substitute for [[Sugru]].<ref>{{Cite web|url=https://www.instructables.com/How-To-Make-Your-Own-Sugru-Substitute/|title=How to Make Your Own Sugru Substitute|website=Instructables}}</ref>

In making [[aquarium]]s, manufacturers now commonly use 100% silicone sealant to join glass plates. Glass joints made with silicone sealant can withstand great pressure, making obsolete the original aquarium construction method of angle-iron and putty. This same silicone is used to make hinges in aquarium lids or for minor repairs. However, not all commercial silicones are safe for aquarium manufacture, nor is silicone used for the manufacture of acrylic aquariums as silicones do not have long-term adhesion to plastics.<ref>{{cite web |url=http://www.aquarium-pond-answers.com/2007/03/aquarium-silicone.html |title=Aquarium Silicone Applications |publisher=Aquarium-pond-answers.com |date=March 2007 |access-date=2012-02-28 |url-status=live |archive-url=https://web.archive.org/web/20120315074424/http://www.aquarium-pond-answers.com/2007/03/aquarium-silicone.html |archive-date=2012-03-15 }}</ref>
