1 - First create your base. Then roll your own tentacles. Use Chavant brand non-sulfur clay.

2 - Completed sea anemone sculpt secured to base board.

3 - Surround with a mold wall that will give you at least 0.5'' on all sides of the mold from the edges of the tentacles.

4 - Be sure that it is centered inside the mold wall.

5 - Hot glue the edges of the mold wall to the base board.

6 - Mold Star 15 silicone rubber is used to create the mold. It has a mix ratio of 1 part A to 1 part B by volume.

7 - Dispense part A.

8 - Dispense an equal part of B.

9 - Thoroughly mix part A and B until there are no streaks. Mold Star 15 does not require vacuum degassing.

10 - Pour the rubber into the lowest part of the mold in a long, thin stream.

11 - Pour rubber in a single spot and let it rise over the model and seek its own level.

12 - Completed pour. Mold Star 15 has a pot life of 50 minutes and a cure time of 4 hours.

13 - To demold your original, cut the plastic mold wall and remove it completely.

14 - Lift the entire mold to separate it from the base.

15 - You will need to cut open your mold open in 4 places in order to demold your original piece. It is helpful to have a friend help hold the mold open while cutting.

16 - Continue cutting just enough so that you can demold your piece. Do not cut your mold all the way to the bottom.

17 - The original sea anemone has been successfully demolded and is ready for casting. All the detail has been captured by the mold rubber.

18 - Align the cut seams and use rubber bands to close the mold.

19 - Align the cut seams in the mold. The mold has been secured with rubber bands. Since we will pour an EcoFlex silicone casting, we need to apply a release agent to prevent bonding.

20 - Since it will be difficult to reach all of the thin tentacle areas of the mold, a liquid release agent is your best option. Combine 2 parts isopropyl alcohol and 1 part dish washing soap.

21 - Mix the alcohol and soap together until blended thoroughly.

22 - Rotate to thoroughly coat the tentacle cavities.

23 - Thoroughly drain the excess release liquid. Allow it to dry for 30 minutes before mixing and pouring your rubber casting.

24 - EcoFlex 00-30 supersoft silicone rubber will be used to make the casting. It has a mix ratio of 1 part A to 1 part B by volume.

25 - Dispense part B.

26 - Ignite fluorescent color pigments that glow under UV light are used to pigment the silicone.

27 - Pre-mix the Ignite red pigment.

28 - Mix the Ignite red into part B until there are no streaks. The pigment is concentrated so a little goes a long way.

29 - Dispense equal part A.

30 - Pour part A into the colored part B.

31 - Thoroughly mix parts A and B together to remove all color streaks. EcoFlex 00-30 has a pot life of 45 minutes and a cure time of 4 hours.

32 - Use a vacuum chamber to vacuum out air bubbles within the silicone. The silicone will rise, break and fall. Your vacuum must pull 29 inches of mercury for complete vacuum.

33 - Slowly pour the vacuumed silicone into the mold cavity.

34 - Allow EcoFlex 00-30 to cure for at least 4 hours at room temperature (73 F).

35 - When fully cured, remove the rubber bands from the mold.

36 - Slowly pull apart the cut seams of the mold. Slowly pull and wiggle your casting out of the mold.

37 - The fully cured casting is life-like and vibrant.

38 - EcoFlex 00-30 is soft and stretchy.

39 - You can vary and combine color pigments or paint your finished piece using EcoFlex 00-30 to create an infinite number of casting effects.

40 - Position and secure your sea anemone in your aquarium.

41 - Your sea anemone casting is identical to the real thing. Tentacles dance freely and realistically in your aquarium.

42 - You can create a variety of sea creatures for your aquarium. View our other videos and galleries to learn how.
