You definitely don't need these things, but...wait, yes you do.
Bottle Cap Gun & Bottle Opener from Hygo
Want to have a nerf war and have your alcohol too? While I wouldn't recommend shooting bottle caps at anyone, maybe this will satisfy that craving. Use this "gun" as a bottle opener, and shoot the cap from the gun. It's totally useless and totally 25% off right now. Watch the demo below and get yours here.
NutriChef Electric Raclette Cheese Melter
Why use a microwave to melt cheese when you can have a separate appliance designed specifically to melt cheese!? Use it to make queso dip or cheesy fries...or melty cheese to go on the panini that your panini maker just didn't do justice. Get it on Amazon here.
The DanceSocks
Simply explained...these are socks to put on over your shoes to make it easier to dance! The socks' website says they reduce stress on ankles and knees and can be used for dance fitness.
