This is designed to be used for students to help them study, but I can think of some far better uses for it. It has a 4 hour max timer and won’t unlock until the timer is up. The ball weighs about 20 lbs which may be a little light for most grown men. This could be perfect for any guys into medieval bondage scenes. I know I could have some fun with it.

Concerned mums and dads set the desired study time on the Study Ball and attach it to their child’s ankle.

A red digital display counts down the “Study Time Left” and the device beeps and unlocks when the time expires.

The prison-style device weighs 9.5 kg (21 pounds), making it difficult to move while wearing it.

It cannot be locked for more than four hours and comes with a safety key that allows the manacle to be opened at anytime.

The ball and chain costs £75 and is sold online at curiosite.com.

The website says: “Quite often, students who are having problems concentrating tend to get up every ten minutes to watch TV, talk on the phone, take something out of the fridge, and a long list of other distractions.

“Were they to dedicate all this wasted time to studying, they would optimise their performance and have more free time available.

“Study Ball helps you study more and more efficiently.”

Designer Emilio Alarcon came up with the idea after a friend likened revision to being in jail.

If you’re looking for a place to start with some inexpensive do-it-yourself kink, spreader bars are one of the easiest places to start. I wanted something really sturdy and more industrial looking, but you could use something as simple as a thick dowel and eye-screws. This was my first attempt at creating something like this, and I had no guide to follow, so it’s not perfect. Click on any picture through this guide to see it full size.

This whole thing only took about 20 minutes to construct and cost about $20. Well worth it for experimenting, compared to the $50+ spreader bars you find at online retailers.

The Parts
2 – 1/2″ metal tubes (I used a 2 ft (legs) and 3 ft (arms) poles – Read Problems section at the end)
4 – U-bolts (2″)
4 – 1/2″ T-connectors

You’ll also need restraints of some kind, and something to connect those restraints to the spread bars

Step 1
Take the U-bolt apart and insert the bar through the T-connector. Tighten the bolts back on. Do this for all 4.

Step 2
Screw the T-connector onto the 1/2″ metal tube. Repeat for all 4. Try to make sure the T-connectors are parallel with each other.

Congrats! You’re ready for some bondage play.

Problems
The 3 ft metal pole is too long. I’m a 6’2 guy and it ended up being a yoke when I tested it on myself. If you can suspend the pole, it might not be so bad. Depends on what you are doing. Also, in the original picture, you may see the clips that I used. Those are too long for this type of use. I would recommend explore shorter clips like carabiners. One last note, the u-bolts don’t fit snug against the t-connector, so they can move around some. I considered using a large eye-bolt with a washer, but I liked the look of this. When you’re shopping for your parts at a hardware store, you may want to consider this option. Just put the eye-bolt through the T-connector, with a large washer on the other side and tighten.

If you have any suggestions, or have done something like this yourself – please share!
