How Do You Crack Open A Slab

1. A Butane torch melts all the plastic and only the coin is left.
2. Sulfuric Acid also melts away the plastic
3. If you use those backyard wood burners, just place the slab in there and POOF, the plastic melts away.
4. Firecrackers known as M80's placed under the slab, light the wick, run, look for coin now not in a slab.
5. Hand to a 5 year old and say don't open this.
6. Place on sidewalk in front of your house with a sign saying please take the plastic but leave the coin.
If none of the above is likeable, do as I do and just cut off all the edges with a Dremel or Saber saw.
