Introduction: UNDERWATER Pumpkin Carving.

In this instructable i will show you how to carve a pumpkin underwater.  Although it seems like a simple task there are a few tricks to make it easier.

Step 1: What You Will Need


For carving a pumpkin underwater you will need:

- a pumpkin
- pen, or marker
- Knife or pumpkin carving kit
- 1-2 bricks or extra lead weights
- (optional) collection bag

and of course scuba gear, unless you can hold your breath for over 2 minutes.

I thought about using my dive knife but its not really suited for cutting out details or curves.

Step 2: Getting Prepared

planning ahead makes this task much easier.

Step1:
Go ahead and cut open the top of your pumpkin and clean out the insides.

Step 2:  (optional)
Draw your design on the pumpkin with a ballpoint pen or sharpie ( use a red sharpie if your worried about not following the lines exactly).

Step 3: Getting in the Water


once you have prepared your pumpkin.  Go ahead and start putting on your scuba gear.

This is where the brick or lead weights come into play.  Even with the top of the pumpkin cut open and you fill it with water, IT STILL FLOATS.  So place your brick or lead weights inside the pumpkin.  I used 1 regular red house brick.  This made my pumpkin neutrally Buoyant, you may have to play around with the weight depending on your pumpkin size.

Also when you get ready to enter the water its a good idea to leave the lid you cut out at your prep station.  It will float away if you try to keep it with you.

For the pumpkin carving knife i just stuck it into the rim of the pumpkin so i wouldn't lose it.

Now your ready to get in the water.

Step 4: Start Hacking Away


once your in the water and settled on the bottom you can start carving your pumpkin.  As you will notice in the video, the pieces you cut out will float away.  So if you dont want to leave them floating around put them in a collection bag.

As you see in the video the mouthpiece i cut out floats away ( i did retrieve it).  The fish are interested in the pumpkin, but dont really care for the taste.

Step 5: Enjoy Your Pumpkin

Enjoy your finished pumpkin


Other Fun:

Take your carved pumpkin on a night dive.  Put your brick or weights back in, tie in some glow sticks, attach the top somehow with nails or staples.  Take your pumpkin to the bottom.You will want to add a few extra pounds of weight than you did before so that it will stay on the bottom where you place it.  Turn off your dive light and enjoy Halloween underwater.

    Do the guts of the pumpkin float as well after being scraped out? This would make the cleanup process MUCH easier! Genius!

    i used to carve pumpkins under water but then i took an arrow to the knee

    As a child, each Halloween that passed I always thought to myself, how would I go about carving a pumpkin under water? I always knew you needed a knife and a pumkin but how would I be able to breathe underwater while carving? now that I read your post I figured out what I was missing...scuba gear! Thank you so much, I'm going to drag my young children to the ocean next halloween and carve pumpkins as a family under water together!

    because i could. Im not the first person to do it either. It was also halloween day. would you carve a pumpkin in space if you had the chance?

    no. if im in space ive got better things to do.

    That is as crazy as my aunt trying to cook while standing on her head!

    They had that up here in Washington, except they even had the gutting under the water.

    i thought about gutting it underwater, but i was trying to make the underwater part quick since i only had 1000psi left and had never carved underwater before. Also I didnt want to make a huge mess.

    Really cool post
    I often wondered how this was done. Thanks I'm gonna try this right away.
