Some kind of clear-dry substance that will laminate the record and keep it together. (like puzzle glue.)
Or you could just hot glue the pieces down.
Posterboard or something to glue the shattered pieces to.
Step 2: Find an old or broken record.
Its okay if it's already broken or has a little chip, I chose an old Capitol, anything will do. One that is firm and not flimsy will be better.
Step 3: Shatter it!
Here is the fun part; time to break it! Drop it, bang it against a table, run it over with a car, I don't know be creative! Bring that record to it's demise. I just dropped it several times. Just don't lose the pieces.
Step 4: Putting it back together.
It's kind of like a puzzle. Put it together and chose the right amount of spacing you want between each piece. Then glue it (or paste it) back together.
Step 5: Congratulations!
You just finished it! Feel free to frame it. Now sit down and watch your friends and family enjoy your masterpiece.
