The Fizzy Nose Spray

TOM had a blocked nose. The nasal spray was empty. He used cola instead. Now his nose is bubbling and he says his brain feels fizzy β€” "finally some pop music inside his head." Chapter 27 is exactly as alarming as it sounds.

The logic, from TOM's perspective, is almost coherent: nasal spray is a liquid delivered into the nose to help with congestion. Cola is also a liquid. The nasal spray was empty. The cola was right there. The gap in this reasoning β€” that cola contains carbonated water, sugar, phosphoric acid, and caffeine, none of which have any business being in a human sinus cavity β€” did not present itself to TOM until the bubbling started.

Chapter 27 is one of the most specifically TOM entries in the whole series. The improvised nasal spray concept requires a very particular kind of optimistic lateral thinking that is almost admirable, right up until the nose starts fizzing.

πŸ“– Chapter 27 β€” The Scenario

TOM had a blocked nose. His nasal spray was empty. He used cola instead β€” spraying it directly into his nostril as a "substitute decongestant." His nose is now bubbling. He reports that his brain feels fizzy. He describes this as "finally some pop music inside his head." What should you do?

A) Tilt his head upside down

Now TOM is upside down and fizzing like a soda can. The cola has redistributed to new areas of the sinus cavity. This has not helped. 0 points.

B)Rinse with saline and call for advice

Saline rinse to flush out the cola from the sinuses, then NHS 111 for professional guidance. Soda up the nose can irritate the sinuses and cause a mess. Use actual medicine.

C)Plug his nose with cereal

The cereal didn't help. But it did confuse the school nurse considerably. TOM now has cola-soaked cereal in his nostril. This is worse than the original situation. 0 points.

D)Offer a straw

The straw made it worse. Carbonated brain, anyone? Introducing more pressure or liquid into a cola-filled sinus is not the solution. 0 points.

Option B is correct β€” and the two parts matter equally. The saline rinse physically flushes the cola from the nasal and sinus passages, which is the immediate priority. Cola in the sinuses causes irritation from the carbonation, the acidity (phosphoric acid), and the sugar β€” none of which belong in that environment. Calling NHS 111 ensures TOM gets professional guidance on whether the irritation needs monitoring or treatment, and confirms there's nothing more serious to address.

πŸ’‘ The Core Rule

Foreign liquid in the nose or sinuses: rinse gently with saline (not more cola, not a straw), then call NHS 111 for advice. The sinuses are connected to the middle ear and throat β€” what goes in there can reach more places than you'd expect. Get professional guidance, even if TOM seems fine and slightly musical.

Why cola in the sinuses is genuinely a problem

πŸ”¬ What Actually Happens When Cola Enters the Sinuses

The nasal cavity and sinuses are lined with delicate mucous membranes that are designed to handle air, filtered through fine nasal hairs, and the gentle saline-like fluid the body produces naturally. Cola is quite different: it contains carbonation (COβ‚‚ under pressure), phosphoric acid (pH around 2.4 β€” significantly more acidic than the sinuses expect), sugar, caffeine, and various flavouring compounds.

Carbonation in a confined space like the sinuses means COβ‚‚ bubbles expanding against mucous membranes β€” causing the tingling, bubbling sensation TOM is experiencing and reporting with entirely too much enthusiasm. The phosphoric acid irritates the delicate lining. The sugar creates an environment where bacteria and fungi can thrive if not properly rinsed out.

More significantly: the sinuses are connected to the middle ear via the Eustachian tube, and to the throat. Liquid introduced into the sinuses doesn't just stay there β€” it can migrate, cause pressure changes in the ear, and introduce the acidic and sugary environment of cola to the throat lining. This is why "call for advice" is part of the correct response, even if TOM seems cheerful about the whole experience.

The correct response β€” step by step

  1. Do not tilt TOM upside down, offer a straw, or add more liquids

    The priority is to remove what's already there, not redistribute it or add to it. Resist the instinct to try creative solutions. This is a rinse-and-call situation.

  2. Rinse gently with saline

    A saline nasal rinse (a neti pot, a saline spray, or a purpose-made sinus rinse bottle) flushes out the cola with a pH-neutral, body-compatible solution. Tilt the head to the side and allow the saline to flow through β€” not up and inward. Pharmacy saline sprays are fine; homemade salt water works at a pinch (ΒΌ teaspoon of salt in 250ml of cooled boiled water).

  3. Call NHS 111 for advice

    Report what happened, the amount involved, and TOM's current symptoms. They'll advise whether monitoring at home is sufficient or whether a check-up is needed for the sinus and ear passages.

  4. Monitor for symptoms over the following hours

    Ear pain or pressure, persistent burning in the sinuses, or any signs of infection developing over the next day or two (increased pain, fever, coloured discharge) should prompt a return call to NHS 111 or a GP visit.

πŸ‡¬πŸ‡§ UK Context

  • Call NHS 111 for any foreign liquid introduced into the nose or sinuses β€” they'll assess based on the specific substance and amount

  • Saline nasal rinses are available over the counter at any pharmacy (Sterimar, NeilMed, and generic equivalents all work well)

  • If TOM's nasal spray was genuinely empty, the correct substitute is a pharmacy saline spray β€” available without prescription, inexpensive, and unlikely to cause fizzing

  • Signs that a GP appointment is needed: ear pain that develops after the incident, persistent sinus pressure, or any signs of infection in the days that follow

  • For actual nasal congestion: steam inhalation, saline sprays, and decongestant medication (available over the counter) are the appropriate options. Cola is not on the list.
