Both work—choose based on how you’ll use them.

• Helium: Best when you want balloons to float. Standard round/shape foils around 18 inches and larger typically float when properly filled and weighted. Keep them indoors for longer float time and avoid heat.
• Air: Great for garlands, walls, centerpieces, letter/number balloons on strings or sticks, and stand-up displays. Air-filled foils don’t float but often last longer.

Inflate slowly to avoid overfilling, and use a weight with helium-filled balloons. You can find portable helium tanks and balloon weights in our party aisle; availability varies by store. For safety, avoid inhaling gases and keep balloons away from power lines.

They’re made differently and behave differently, so each suits different needs.

• Appearance: Foil balloons have a shiny, printed surface and come in specialty shapes (characters, numbers). Latex has a classic matte or glossy look.
• Longevity: Foil typically holds gas longer than latex under similar conditions. Air-filled foils can look good for days or more.
• Sealing: Most foils have a built-in self-sealing valve; latex usually needs to be tied or sealed separately.
• Use cases: Choose foil for standout themes, large numbers/letters, or detailed graphics. Latex works well for bulk decor like arches and fillers.

Mixing both can create dimension and a budget-friendly display.

1. Pick your fill: Helium for floating; air for garlands, walls, or sticks.
2. Find the valve: Locate the small opening on the tail of the balloon.
3. Insert nozzle or straw: Use a helium nozzle or a hand pump. For air, a plastic straw can help guide airflow.
4. Inflate slowly: Stop when the balloon looks smooth and firm. Avoid overfilling to reduce seam stress.
5. Seal: Most foils self-seal—remove the nozzle and press the valve flat. Attach ribbon or a balloon cup/stick as needed.

Consider a weight for helium balloons. Availability of helium tanks and accessories varies by store.

Timing varies based on size, seal, and environment.

• Helium-filled: Many foil balloons can float for roughly a day to several days, sometimes longer, depending on conditions and balloon size.
• Air-filled: Often last longer since they’re not floating; they can look party-ready for multiple days when kept indoors.

To help them last: keep balloons indoors at moderate temperatures, avoid direct sun and hot cars, use a proper seal, and add a weight to reduce tugging. If a self-sealing valve allows, a gentle top-off may help, but avoid overinflation. Results can vary with handling and room conditions.

1. Deflate carefully: Insert a drinking straw gently into the valve until you feel air release. Press the balloon slowly to expel air.
2. Flatten and fold: Once deflated, smooth it out and fold loosely to avoid creases on seams.
3. Store smart: Keep in a cool, dry place away from sharp objects and direct sun.
4. Inspect before reuse: Check for small leaks or seam wear. If the valve is intact, you can refill with air or helium as appropriate.

Reusability depends on handling and the balloon’s condition. Keep extra ribbon, weights, and cups/sticks on hand for quick refreshes.
