An-diugh, bidh Calum D貌mhnallach, Kerry Anne Nicle貌id agus na Sealgairean Sp貌rsail a' toirt s霉il dhan fh脿nas. Faigh a-mach mu innealan a thug buaidh air teicne貌las f脿nais a tha sinn fhathast a' cleachdadh, mar uidheaman gun ch脿ball agus biadh re貌thte tiormaichte.

Bidh na Sealgairean Sp貌rsail a' togail rocaid dhaibh fh猫in, a' leantainn prionnsabail sruth-chruthachd gus am bi an cruth as fhe脿rr oirre son sg猫ith tron 猫adhar. Feumaidh iad p矛ob phlastaig, p脿ipear agus cairt-bh貌rd son toiseach t貌iseachaidh. Bidh iad cuideachd a' rannsachadh mar a tha meanbh-iom-tharraing ag obair ann am f脿nas. Air ais san sti霉idio, tha Calum agus Kerry Anne gan sgeadachadh fh猫in ann an aodach f脿nais agus a' cleachdadh baili霉n c貌mhdaichte le foidhl gus obrachadh a-mach d猫 th' ann an toll-dubh.

Today's focus is on outer space. Find out how things work and discover the history of developments invented for space travel which we still use today, like cordless power tools and freeze dried food.

The History Hunters make their own rocket using the principles of aerodynamics to make sure it's the best shape to fly through the air. First, they'll need some plastic piping, paper and cardboard. The second challenge examines how microgravity works in space.

Back in the studio, Calum and Kerry Anne get dressed up in space gear and use a balloon wrapped in foil to work out what a black hole is.
