Svör við spurningum á vísindavefnum (http://www.visindavefur.is/author.php?id=388 )
- Hver er innri gerð snjókorna? Eru engin tvö snjókorn eins?
- Hvernig myndast frostrósir á rúðum? Myndast þær annars staðar?
- Hvers vegna myndast kuldi þegar salti er stráð á ís, til dæmis á tröppum húsa, og hvers vegna breytist ísinn þá í vökva?
- Hvers vegna frýs vatn?
- Götur eru saltaðar til að svellið bráðni, en skíðabrekkur til að fá harðfenni. Hvernig má það vera?
- Hvers vegna dragast sum efni saman þegar þau blotna, til dæmis kaðlar, snæri og ýmis vefnaður? Hvers vegna þenjast þau ekki út við að bæta við sig efni?
- Hvers vegna verða kaffiblettir dekkstir við jaðarinn þegar þeir þorna?
- Af hverju er auðveldara að þurrka bleytu af borði með blautri, vel undinni borðtusku en þurri?
- Hvernig verkar strokleður?
- Af hverju kemur ekki gat á plastglas sem er fyllt með vatni þegar kveikjara er haldið undir því?
- Hvernig verkar drullusokkur?
- Þegar maður kastar skopparabolta í gólfið með snúningi, af hverju kemur hann til baka með öfugum snúningi?
- Afhverju límist límtúban ekki saman?
- Afhverju fylgja litlar kísilkúlur í hvítum pokum oft með hlutum eins og t.d. kíkjum?
- Hvers vegna koma krullur á borða þegar maður strýkur honum eftir skærum?
