Getting a Reacher Grabber

You can buy a reacher grabber online, just be careful to buy the "suction cup" style reacher grabber instead of any other kind. We generally like the Vive brand ones, but this is a simple enough tool that not much can go wrong.

Here are a couple of sample links:

  2. Stire each compound within its container

  4. Pour the mixed silicone compound into each hole in the mold (8 of them)

  5. Wait until the silicone cures, then remove the tips
