Introduction: The Ultimate Banana Guard

Picture of The Ultimate Banana Guard
When ever I take a banana In my pack for mountain biking it always gets squashed.

Plastic guards are all very well for walkers but they don't stand up to sliding down a hillside with a bike on top of you.

To this end, I made the Ultimate Banana Guard and it works.

In the video you will see that it resists, impact, abrasion, attack, squashing and not least, for the sake of fun, fire.

Please vote if you like this Indestructible.

No bananas were harmed in the making of this video.

Step 1: Cutting the Tube.

Picture of Cutting the Tube.

I imagined building a hinged metal box but then I remembered the bed frame on my metal pile, ( everything eventually gets used ).

The curve was perfect.
I measured it against a few bananas and cut a suitable size.

Step 2: Making the End Caps.

Picture of Making the End Caps.

The bed frame had plastic plugs for feet.
I removed these and cut plywood discs , with a jig saw, to fit inside.
This will stop the ends of the tube from being deformed under extreme pressure.

Step 3: Adding the Ring Pull.

Picture of Adding the Ring Pull.

I wanted to use a ring pull but could find nothing suitable.
I found some toggle bolts from a lawn mower.
I tried one, and although it would do, it wasn't the look that I craved.
I searched my house again and found a little bracket and then a hose clamp.

It was a much better design.

Step 4: Lining the Tube.

Picture of Lining the Tube.

I cut out discs of bubble wrap  and glued them together; I stuck this in the base.

Four strips of bubble wrap were glued to the inner tube.

The lid has no padding because the banana has its own stalk as protection.

Step 5: Painting.

Picture of Painting.

I wanted this to look tough and although I usually use matt black for everything, I felt that this project warranted the military touch.
I had in mind the colour and stencil look of ammunition boxes or grenades.

I looked up the Russian, Chinese and various other countries' names for banana but none really looked that good so I just chose,          " B.GRENADE ".

I used matt olive paint for the tube and yellow for the stencil.

Step 6: Testing.

Picture of Testing.

That is pretty much it; please see the video for the testing of this guard.

It held up against impact, abrasion, attack, squashing and fire.

I'm off to eat a banana.

Hillarious demonstrations and replies to the comments. I have only one contention in the video: the banana is not indestructible; it was protected. (Also, I hope you weren't in too much danger from ricochet while shooting (lol) at it.)

Well you should always guard your banana

dizzle976 (author)2014-10-25

honestly, this is one of the better instructables ive seen. great job man....

Like the US Pineapple and Lemon grenades? A new development?

Tee hee hee! I never thought of that; good one.

Dear Potaomansoup,

Thank you very much ; I am amazed and happy.
My money was on the Titanium ring or chainmail.

Haha!! What a unique and functional idea!

Thank you for your nice comment.

That's amazing

I'm happy that you liked it.

Forget the banana guard (although it's cool), I want that flame thrower!

FriendOfHumanity (author)soshimo2013-04-10

I love the smell of bananas in the morning.

soshimo (author)FriendOfHumanity2013-04-10

It smells like.... victory!

Why arent there any Apple guard posts?

aristide202 (author)2013-03-12

Very nice instructables, I have they same bananas squashing prolem too but at the moment I don't have anything like you bed frame in my scrap deposit.

Dear Aristide,

Thanks for the comment.
Good luck with the search for a scrap bed frame.
You could always try a pipe bender; as mentioned by Oilitright ( a few comments below).

Kind Regards


intellio (author)2013-03-11

Just Cool. Good job. What inspired you to save a banana?

Dear Intellio,

Thanks for the comments.
I just tried to think of  something in my everyday life that was regularly broken or spoiled and my brain said ' ,' banana'.
i always seemed to squash one when I went mountain biking.

Kind Regards

I instantly thought of the Imgur communities reaction to something like this; however I don't want to post it on your behalf. I think they would love to see your Banana Guard! :P

FriendOfHumanity (author)pkemp922013-03-10

Dear Pkemp92,

I'm too out of touch to know what Imgur is but thanks for the advice; It sounds interesting, I will look into it.

Kind Regards


oilitright (author)2013-03-09

Very ingenious and useful. Also very satisfactory photographs and demo video was top shelf. Have you noticed any tendency for bananas to over ripen to quickly? I am going to try to make one. I don't have a bed frame but I do have a pipe bender. For the plugs I'm going to try and use pressure test plugs.

Dear Oilitright,

Thank you for the kind words.

No, I have not noticed a tendency for over ripening because my bananas are only kept in there for about three hours; and I like them all speckledy brown anyway.

Your version sounds interesting; why not post a picture when it's done ?

Kind Regards


just1jane (author)2013-03-09

It has my vote. Clever, useful, and fun. Just don't take any bananas with you to the airport.

Dear Just1jane,

Thanks for the vote.
No, good point, it's not airport-official-proof.

Kind Regards

Ok, good work, but doesn't resist a nuclear bomb, he-he-he !! ;-)

FriendOfHumanity (author)asegade2013-03-09

Dear Asegade,

Doh! You found the weak point.
Thanks for the comment.

Kind Regards


No, No, No !   Boldly make the claim, "Proof against 50 Megaton Nuclear Bomb Blast".

If anyone argues, challenge them to prove you wrong.  

As long as you do not challenge Chinese government officials, I think you'll find, no takers.

Dear ElectroFrank,

Yes, good point, you are right.

To use the ' parlance of our times ' , Prove me wrong.

Thanks for the comment.

Kind Regards

Appears that the banana guard would work as a wheel chock in a pinch or the driver was very timid about running over the thing. The bananas that arrive here seem to vary in size so one would have to construct a guard to accommodate the largest of them. Electrical conduit sweeps might be a ready source for the tubing While not as rugged the PVC variety would be lighter. Personally I would pack dehydrated bananas, but the instructable is well done as is the video production.

FriendOfHumanity (author)static2013-03-09

Dear Static,

I could have made it longer, with part of it straight, to accommodate big ones but I always buy the cheapo small bananas.

PVC tubing instead of steel is a good idea for bananas that are not planning on being run over by Land Rover or set on fire.

Thanks for the comments.

Kind Regards


AJMansfield (author)2013-03-07

The bananaguard really wouldn't be much fire protection, actually, because the banana would still get hot and would still get all sticky, even if it didn't burn.

Never interrupt me when I'm eating a banana.

LaffyDuck187 (author)2013-03-09

I will stuff bacon and ammo into this to survive the zombiepocalypse but is it tested to be zombieproof? If the zombie bites my case is the banana still safe to eat?

Dear LaffyDuck187,

Good question.

On your first point; I think that a zombie would be extremely lucky to get the lid off ( but you might want to add a padlock just to be sure).

On your second point; According to Max Brooks, author of The Zombie Survival Guide,
'A person can only become infected through "direct fluidic contact" , including bites and direct contact with zombie wounds and remains with open wounds on humans.'

I hope that this helps.

Kind Regards

Dear ChrisE123,

I used to love banana chips but then I read that  . . .

" One of the largest differences between the banana in its natural form and banana chips is the total and saturated fat content. Banana chips supply a whopping 9.5 g of saturated fat per ounce, of which 8.2 g is saturated. In contrast, a natural banana contains less than 1 g of total fat. The saturated fat that is added in the frying process can be expected to have a negative effect on health, particularly in terms of the cholesterol and the heart. "

Kind Regards


In that case dehydrate them yourself. Slice the banana thinly, dip in lemon juice or citric acid (crush up 3 or 4 Vitamin C tabs and mix with water) and the dry in the oven or a dehydrator or even in the hot sun. No additives other than the lemon/citric acid/Vitamin C

Dear Mkieth54,

Righteo, I will try this ( on top of my woodstove).

Thanks for the info.

Kind Regards


static (author)FriendOfHumanity2013-03-07

Sounds like there are banana chips, and there are banana chips. The dehydrated variety shouldn't contain no more fat than a fresh banana if you limit yourself to on banana's worth of chips.
