Even though I prefer Blogger, I have a Wordpress blog at Marti's DIY for those who can't comment here. Or you can email me. (Right sidebar)

By the way, if you use Blogger and can’t comment on WordPress blogs, change to a different browser. I found that I couldn’t post to WordPress when using Firefox.

Apparently, some Wordpress blogs won't let me comment if I use my blogger email either. So if you get a comment from me from thisemaildoesntexist@_________, that's why.

Cheap Security Alarm to Prank Friends and Family

I really dislike greeting cards because they are such a waste of money. I resent paying $3.50 for a card to go with a gift, and I really feel bad for the person who gives one to me. They paid good money and stood in line for who knows how long to pay for it, so I can read it for three seconds and then throw it away. I am not one of those sentimental people who keeps greeting cards. I have enough paper cluttering my existence.

However, I received a birthday card last year that I just couldn't throw away. It was one of those greeting cards that plays music when you open them, and I just couldn't throw away something that seemed to have a use. Or did it? I kept it for two months until I thought of something. They can be taken apart to make a gag security alarm. I cut out the part of the card with the chip and speaker and glued it to one of those freebie magnets from the dentist's office. Then I slipped a regular strip of paper under the connection and taped it to the door so it can be pulled out when the door opens.

Actually, I put this on the side of my freezer with the paper taped to the freezer door; it is completely out of sight from anyone opening the freezer. It's been a lot of fun to hear everyone when they open the freezer door and the music starts playing. Unfortunately I couldn't get a picture of it on the freezer so put it on the back door for the photo shoot.

I can think of a lot of fun uses for this, on the cookie jar (of course it would have to be attached to a metal cookie container or attached in another way), on a hotel door, on the tv cabinet, or anywhere else you want to startle people. Watch out though, Brownie almost dropped a glass when she opened the freezer the first time.

Until next time, may you have blessings and fun pranks,


  1. I had no idea the cards had that large of a speaker to them! Good thinking, sounds like something fun to do. My 13 yo already used a science experiment kit to make his version of an alarm that was way too quiet, so I might have to see if I happen to have anymore old musical cards sitting around for him to work with now.

  2. The speaker may look bigger in the picture, it's 1-1/2", but loud enough to startle.
