Just Play is celebrating with a giveaway of 75 limited-edition, gold-plated Slinkys between Friday, Aug. 28, and Tuesday, Sept. 1. To enter, fans can share photos or videos on Instagram showing why they love Slinky, such as coming up with a Slinky dance, showing off their Slinky postage stamps, racing a Slinky with their pet, or anything social media-worthy.

Instagram accounts must be set to public and all entries must include the hashtags #NationalSlinkyDay AND #GoldenSlinky for a chance to win one of the special, gold-plated prizes. Just Play will select 75 winners at random from the submissions. May the best Slinky win!
