This could be done with virtually any toy or figurine but the more detailed it is the harder it may be to get it to come out perfectly.


  • Instamorph Moldable Plastic
  • Legos®
  • Glass dish for heating
  • Sharp Kitchen Knife (Adult Supervision Required!!)
  • Rolling Pin or flat surface to use as a press
  • Cooking Spray

Step 1: Heat Your Instamorph

Pour your instamorph in a glass dish and cover with water.

Heat in the microwave until instamorph becomes clear and the beads stick together.

Step 2: Prepare Mold

Once instamorph is heated carefully remove from the dish and put on a flat surface sprayed with cooking spray.

Use a rolling pin or the bottom of a pan, cover with cooking spray, and then press the instamorph until it is the thickness you desire for your mold.

Step 3: Trim Excess

Using a sharp knife cut off the excess plastic so you have a square mold.

Submerge your plastic in the hot water for another minute.

Step 4: Create Mold

Gather Legos® and remove your plastic mold from the water.

Quickly press legos® into the mold in the desired order.

Let Cool.

Step 5: Remove Legos®

Once the mold is cooled remove the legos® (they should pop out fairly easily) and voila, you have a lego® mold for jello or chocolate.

<p>Hi - an intriguing project indeed!</p><p>Two questions ...</p><p>1) Is InstaMorph/PCL food safe? (This one I mostly answered myself - Google led me to several links talking about applications of medical-grade PCL (polycaprolactone), but went on to say while that grade is guaranteed pure, it is also substantially more expensive than retail-grade. Beyond that I didn't find much more than conjecture that what we can get through retail may or may not have additional contaminates.)</p><p>2) How easy/difficult is it to remove cooled chocolate from a friendly plastic mold, since it is inflexible?</p><p>Thanks!</p>
<p>Very nicely done! </p>
