Step 10: Thrash, Rinse, Repeat

Once freed from the mold you’re left with a skatepark obstacle that kind of feels like an ice-cold brick. Fresh out of the freezer it’s rock solid and great for performing tricks on as the frozen surface is actually quite smooth. But the catch with this concrete alternative is that your time at the skate park is limited by how warm your home is and how quickly the material will thaw and become soft once again.
That’s also one of the benefits of Tech Deck’s D.I.Y. concrete material. Real concrete remains rock solid until you come at it with a jackhammer, but you can just drop this molded creation into a bowl of hot water again for five minutes and it will return to its soft, mushy state, allowing it to be molded into something else.
The Tech Deck D.I.Y. Concrete kit will officially be available starting in August for $15, and it includes an exclusive Tech Deck miniature skateboard. Water and a freezer are not included.
