Gaza ‘bottles of hope’ unlikely to succeed, experts warn

[CAIRO, SciDev.Net] As Gaza shows signs of widespread starvation, with food and medical supplies only trickling in, unconventional initiatives are gaining traction online.

Activists in the region tried to send food to the besieged area by floating it in plastic bottles across the sea — an idea that has raised both hope and debate.

The Middle East and North Africa edition of SciDev.Net, through its podcast Sharara (meaning spark) highlighted these symbolic efforts and looked at whether they are backed by science.

Supporters describe the sending of so-called “bottles of hope” as acts of civil resistance, while experts caution against overestimating their feasibility and warn of environmental risks.

The idea was first floated by Egyptian engineering professor Mohamed Aly-Hassan, currently based in Japan, who described it as a “desperate cry of hope”.

He called for alternative ways to break Gaza’s maritime isolation, amid the ongoing blockade on goods and people in and out of the war-torn territory.

Online activists quickly shaped the plan: seal dry food such as rice, lentils, or beans inside airtight plastic bottles, leave some air inside so they float, and drop them at least four kilometres from the shore, at an angle that avoids the waves pushing them back.

Some say that the winds and sea currents in the Eastern Mediterranean could deliver the bottles to Gaza’s beaches in three to four days.

However, marine scientists remain skeptical. Ahmed Radwan, professor of physical oceanography at Egypt’s National Institute of Oceanography and Fisheries, told Sharara that the probability of bottles reaching Gaza was “extremely low, no more than five per cent”.

“The Mediterranean is shaped by complex circulation systems, including the North African currents and local eddies off Marsa Matruh and Port Said,” Radwan explained. “Such patterns often divert floating objects to distant coasts — as far as Greece.”

He also warned that the effort could worsen the region’s already severe plastic pollution if most bottles fail to reach their intended destination.

Zakaria Bakr, head of the General Syndicate of Fishermen and Marine Production Workers in Gaza, confirmed that no bottles have arrived so far.

Strong currents, maritime security barriers, and the need for precise navigation make the plan highly impractical, he said, dismissing viral videos claiming successful landings as “media propaganda”.

Fact-checkers have also debunked some images as being AI-generated.

But the debate has also led to new ideas. Egyptian engineer Hesham Nagy suggested using strong polystyrene boxes with small rudders that work with the current, each able to carry about five kilograms of food.  This, he argued, could improve delivery rates compared to bottles, whose success he estimated at below one per cent.

Others proposed assembling small rafts from bottles and wire, fitted with makeshift sails. But Radwan cautioned that elaborate designs might reduce efficiency while increasing environmental risks.

Experts say that if these emotionally charged efforts are to be more than symbolic, they need real planning, using ocean science, weather forecasts, and working with Palestinian authorities to handle the supplies when they arrive.

But activists insist that symbolism matters. Even if little food ultimately reaches Gaza, they say, these acts serve as a reminder of the area’s suffering under blockade — and a call for international solidarity.
