Behind the Scenes of the Tie Not Battle Pump video.

Make water balloons in under 10 seconds. Anywhere!

We love water balloon fights. But before we stumbled across the Tie-Not Water Balloon Filler and Tying Tool, creating ammunition was always a chore. However, the only problem (as teeny tiny as it is) with the Tie-Not Filler is that it isn't 100% portable. It must be attached to a hose.

Enter the Tie-Not Battle Pump by Kaos. This sucker is the perfect addition to your water balloon arsenal. The one-gallon canister features a pump, nozzle, and a built-in Tie-Not Tying Tool. So, no matter where you are, you can quickly create more water grenades!

Frequently Asked Questions

Question: How is this different than the regular Tie-Not?

Answer: The Tie-Not Water Balloon Filler and Tying Tool must be attached to a hose. The Tie-Not Battle Pump is portable and doesn't require a hose. Simply fill it up from a faucet and you're ready to go!

Question: Should I buy this or the regular Tie-Not?

Answer: This is like asking if you should have a navy or an air force. You need both, son! The Tie-Not Water Balloon Filler and Tying Tool hooks up to a garden hose for constant ammo creation. However, your position is fixed — and thus vulnerable to attack. The Battle Pump, on the other hand, is highly portable. You can sneak behind enemy lines, create ammo, and drench the opposition.

Think of it another way (which also allows for a cross-promo): The Battle Pump is like a B-2 Stealth Bomber whereas the regular Tie-Not is like an aircraft carrier.

Question: How many balloons can I make from one fill-up of the Battle Pump?

Answer: You can make approximately 20 average-size water balloons. The Battle Pump has a capacity of one gallon (128 ounces). Your typical water balloon holds 5-6 ounces of water.

Question: Can I choose my color of Battle Pump?

Answer: No. The Battle Pump was originally available only in a blue & gray combo (as shown in our video). That color scheme has been replaced by a series of brighter (and in our opinion, better looking) color combos.

The color combinations are random. However, they all look good! Plus, it's their function (quickly making water balloons) which is most important! So, don't sweat the color. We'll send you a perfectly beautiful one!

Question: Aren't you going to show someone getting pummeled in the face with a water balloon?

You bet your sweet freedom we will!

Nothing better than hitting the boss in the face.
