A magazine competition invited people to come up with "invented" inventions of the cyber-age.
For example, a solar powered clothes drier (a rope) and a hand-held word processor (a pencil). Can you guess what this is?
It is a portable arcade. A hand-held amusement resource with no cartridges or batteries. Access games of speed, dexterity, memory, cunning. Produce magical effects or construct lofty towers. Some games can increase your income.
Can you guess what it is??
ok ....
i'll re-phrase the question...
How do you time Dirtygirlie's 7 minute session with her vibrating love egg armed only with a 9-minute, 11-minute and a 14-minute eggtimer?
oh...
and can we watch please...?
:P
Turn the 9 and 11 timers over together. When the 9 runs out of sand immediately turn it over again. Put the egg in the pan when the 11 runs out - there will be 7 minutes of sand left in the 9 timer........... I think!

Right last one, (otherwise certain members will really really dislike me :shock: )
Bob was having a big party. He decided on a technique to get lots of people to come. He invited his five closest friends and said that they could each invite 4 people.
Each of those could invite 3.
Each of those could invite 2.
Each of those could invite 1.
Overall, how many people did Bob invite to his party?
If only i hadn't spent ages trying to do long multiplication i might have nipped in before you :doh:
nope

25 1x1
some 2x2..? 3x3..? 4x4..?
