A vacuum company is helping to spread some Christmas cheer with a new futuristic Christmas tree.

Six engineers at Dyson have worked to build a 12 foot Christmas tree, whose ornaments float in the air (below).

The tree was created by using transparent hoover tubes as a base, with air sent up through the tubes to help nine purple ornaments hover in the air. As a star, the engineers also used a yellow foam ball.

The idea is based on a fluid dynamics called the Bernoulli’s principle, which states — according to a Dyson engineer — that “pressure in a liquid or gas decreases as it moves faster.”

And though it looks relatively simple, the tree was not easy to design.

“We went through loads of iterations, but we finally settled on a design” said one engineer. “Whether it was the weight of the baubles, or the angles of the pipes or ‘branches’, there was so much to consider.”

The Irish Times reports that the current spell of mild weather will soon be interrupted – with parts of the west and north-west of the country even having a chance of a white Christmas.

It’s reported that temperatures will fall on Christmas Eve, breaking the spell of mild weather that has seen this December become one of the warmest on record so far.

Met Éireann say that the wintery showers will turn to sleet and then snow on higher grounds on the coastal fringes of Donegal, Mayo and Galway.

It’s thought to be a bracing way to start the day, with fresh air and cool waters believed to revitalise the body after a big breakfast and prepare one for a turkey dinner.

For many people, the a Christmas Day sea swim is as much a part of the festive calendar as carols and presents.

And now The Irish Times have released the top places for a swim this December 25th, so you know you’ll be in good company if you hit the following spots:

Skerries, Co Dublin

Forty Foot, Sandycove, Co Dublin

New Pier, Wicklow Harbour

Rosslare, Co Wexford

Kilkee, Co Clare

Lough Lannagh, Castlebar, Co Mayo

Maths students from University of Sheffield have contrived a formula for decorating the perfect Christmas tree.

The fantastic festive formula ensures the correct ratio of lights, tinsel and baubles can be used to give your Christmas tree the perfect look.

Using their ‘treegonometry’ formula, the standard 5ft tree would need 31 baubles, 776 cms of tinsel and 478 cms of lights, with 15cm star or angel to top it top.
